Vinyl Chloride Monomer (VCM) Key data describing supply and demand for vinyl chloride in 1978 are given below. VINYL CHLORIDE MONOMER SUPPLY/DEMAND - 1978 Millions of Thousands of Pounds Metric Tons Production Annual Production Capacity (year-end, nameplate) Domestic Consumption Exports 6,955 8,695a 6,065 899 3,155 3,944a 2,751 408 a. Includes 500 million pounds (227 thousand metric tons) of capacity that was operated by PPG in Puerto Rico until the end of 1978. SOURCE: U.S. government publications, trade literature, and CEH estimates. In 1979, total VCM demand for domestic use is estimated to be 6.4 billion pounds (2.9 million metric tons); U.S. exports are expected to be about 1 billion pounds (454 thousand metric tons). Capacity to meet this demand level is sufficient in spite of the loss of PPG's Puerto Rican capacity. B. Polyvinyl Chloride (PVC) Resins The 1978 PVC supply/demand balance is characterized by the following figures. PVC RESIN SUPPLY/DEMAND - 1978 Millions of Pounds Thousands of Metric Tons Production Annual Production Capacity (mid-1978, nameplate) Domestic Consumption Exports 5,724 6,890 5,570 252 2,596 3,125 2,527 114 SOURCE: U.S. government publications, trade literature, and CEH estimates. Effective U.S. PVC capacity in 1978 was, overall, 12-15% less than nameplate because of operating deficiencies and also as a result of regulatory compliance with VCM control standards. On that basis, U.S. production capacity, overall, operated at nearly full utilization in 1978. The incremented capacity increases that became operational in the second half of 1978 and the first half of 1979 were comparatively minor; total mid-1979 U.S. PVC production Chemical Economics Handbook - SRI International December 1979 POLYVINYL CHLORIDE RESINS Plastics and Resins 580.1881 E capacity (nameplate) amounted to 7,115 million pounds (3,227 thousand metric tons). Since more stringent EPA control requirements took effect in October 1978, however, copolymer and dispersion resin capacities were further reduced in their effectiveness. The overall (predominantly suspension homopolymer) capacity effectiveness is believed to have im proved to about 90% of nameplate, however. With domestic PVC demand for 1979 estimated at 5,890 million pounds (2,672 thousand metric tons) and PVC exports at 260 million pounds (118 thousand metric tons), capacity utilization again was about 96%, overall, but copolymers and dispersion resins were actually in short supply. Projected Demand A. Vinyl Chloride Monomer (VCM) Monomer demand for domestic use will parallel PVC demand growth, and on that basis is estimated to increase an average of 6% annually between 1979 and 1983, leading to a projected domestic monomer demand of 8.07 billion pounds (3.66 million metric tons) by 1983 (non-PVC uses are projected to grow at about the same rate). Monomer exports are expected to run at the 800 million pound-per-year (363 thousand metric tons) level through 1981 and then drop to about 600 million pounds (272 thousand metric tons) per year. Thus, total VCM requirements are estimated to be 8.6-8.7 billion pounds (3.9 million metric tons) in 1983. B. Polyvinyl Chloride (PVC) Resins Long-term demand for PVC in its major markets is expected to remain stable, since PVC plastics uses are firmly established and there is no competitive material that can readily replace PVC. The following table summarizes demand projections for major PVC end-use markets. ESTIMATED CONSUMPTION OF PVC RESINS - 1978 AND 1983 1978 1983a Average Annual Millions Thousands Millions Thousands Growth Rate, of of Metric of of Metric 1978-1983 Pounds Tons Pounds Tons (Percent)' Construction Consumer Goods Electrical Uses Packaging Transportation Home Furnishings Miscellaneous Exports 3,000 710 510 460 280 220 390 250 1,361 322 231 209 127 100 177 113 4,410 840 610 550 330 260 460 300 2,000 381 ' 277 249 150 > 118 209 136 8% 3.5% Total 5,820 2,640 7,760 3,520 6% a. Data have been rounded to the nearest 10 million pounds. SOURCE: CEH estimates. Chemical Economics Handbook - SRI International 1 iDecember 1979 POLYVINYL CHLORIDE RESINS Plastics and Resins 580.1881 F The above projections assume an average annual GNP growth of 3.5-3.7%. Construction is by far the largest market for PVC; in fact, one sector of this market, pipe and conduit, accounts for the bulk. PVC resin consumption for pipe has become the decisive factor in the determination of overall PVC demand. In 1978, 2.3 billion pounds (1.0 million metric tons), about 40% of the total consumption, were used in this market, which is expected to consume 3.3-3.4 billion pounds (1.5 million metric tons) by 1983. Any major deviation of PVC consumption for pipe from the projected figures would, therefore, cause significant change in the projected overall PVC consumption. PVC pipe and conduit markets will continue to grow primarily as a result of the ongoing replacement of conventional pipe and tubing. The remaining potential for this growth is particularly large for sewer pipe (10-13% annually), although in terms of PVC requirements, municipal water pipe for urban areas continues to be an important growth market. By contrast, almost no growth is seen in the rural water pipe market in general, although this varies somewhat among geographic regions. In the conduit field, growth is expected to continue and will be the strongest for electrical conduit. Comparatively low growth rates are expected for drain, waste, and vent (DWV) pipe, and for irrigation pipe. Demand for other rigid PVC building products is generally expected to increase at a combined average annual rate of at least 8% between 1978 and 1983, with siding as the leading product. Flooring, however, is not expected to grow at that high a rate. The other PVC market categories represent generally mature or highly penetrated markets; some segments are not expected to grow at all and might even decline (e.g., shower curtains, garden hose, baby pants), while others will increase (e.g., wall coverings) resulting in modest overall growth. Electrical uses represent a market that is expected to parallel construction activity, resulting in somewhat better gains for PVC than more consumerrelated markets. PVC resin prices are firm as of mid-1979; they reflect added costs for controlling vinyl chloride monomer as well as the industry's need to continue expanding.

Includes 100 million pounds (45 thousand metric tons) for non-PVC uses. Reduction (from total PVC demand) to allow for comonomer used in copolymers and increase to allow for VCM monomer losses were assumed to be equal. d. Includes 260 million pounds (113 thousand metric tons) for exports. SOURCE: CEH estimates. According to these estimates, domestic VCM supply will be barely adequate in 1980 if domestic demand continues to increase as projected and exports stay up. Relief will come in 1981 when new capacity by Georgia-Pacific and by PPG comes on stream. PVC supply will be sufficient, overall, through 1980, but in early 1981 supply could become tight until new capacity by Tenneco and by Shintec becomes operational. (Late in 1981, additional new capacity by BFGoodrich and Conoco is expected to come on stream). Of the eleven U.S. producers of vinyl chloride monomer, Dow Chemical is the largest, followed by Shell, Diamond Shamrock, BFGoodrich, and Conoco (78% of the total U.S. capacity). Georgia-Pacific is scheduled to start up a one billion pound-per-year VCM plant in late 1980. Of the 21 PVC resin producers, BFGoodrich remains the largest by far, followed by Tenneco, Firestone, Diamond Shamrock, Conoco, Borden, and Stauffer (67% of total U.S. capacity). Georgia-Pacific will have sufficient capacity in early 1980 to become one of the four largest U.S. PVC producers. December 1979 POLYVINYL CHLORIDE RESINS Plastics and Resins 580.1882 A DESCRIPTION Vinyl Chloride Vinyl chloride, the monomer for polyvinyl chloride homopolymer and copolymer resins, is a gaseous, reactive intermediate derived from ethylene or acetylene. Generally, 1.025 pounds of vinyl chloride are needed to manufacture 1.0 pound of PVC homopolymer. (A factor of 1.03 is sometimes used). Polyvinyl Chloride Resins The term polyvinyl chloride (PVC) resins includes vinyl chloride homopolymers with the repeating unit-CH^CHCl-, and copolymers of vinyl chloride with varying amounts of vinyl acetate, ethylene, propylene, vinylidene chloride, or acrylates. Generally, these resins are in the form of white powders or granules that, after compounding with auxiliary ingredients, are converted into a large variety of plastic end products through several types of processes. Because PVC resins jure thermoplastic, these processes employ heat (except in the case of coating resins, which are processed by dissolving them and applying them from solution). The general performance characteristics of PVC plastics include mechanical toughness, fairly good weather resistance, resistance to water and to many chemicals (including strong mineral acids), fairly good electrical insulating properties, and a pronounced thermoplastic character, i.e., the manufactured articles tend to be soft in a warm environment and increasingly stiff in colder surroundings. PVC plastics that contain little or no plasticizer, therefore, tend to be sensitive to impact at low temperatures. All of these properties depend entirely on the exact composition of the compounds used. % The processing and performance characteristics of PVC resins can be varied with the molecular weight, which for most commercial PVC resins lies between 50,000 and 120,000. Molecular weight distribution, particle size, and particle surface characteristics are other variables that are controlled in resin production and that vary among the different grades of PVC resins. Of particular importance to the characteristics of PVC plastics is the presence or absence of plasticizer. Most PVC plastics produced in past decades have been flexible types containing plasticizer. The processing of plasticized PVC is relatively easy to carry out, compared to that for PVC compounds containing essentially no plasticizer. Processing of the latter, which are used for the production of rigid PVC plastics, is technically more demanding. The properties of plasticized PVC plastics depend greatly on the exact amounts and chemical types of plasticizers used; it is common to employ mixtures to achieve the desired properties. Although the great majority of PVC resins used to manufacture PVC plastics are homopoly mers of vinyl chloride, copolymers are still essential in some processes where they are used alone or in admixture with homopolymers. The most important commercial copolymers of vinyl chloride are those used for phonograph records and those for vinyl asbestos floor tile; these have an average vinyl acetate content of about 13%. Other PVC-vinyl acetate copolymers are used in calendering and extrusion formulations; these have an average vinyl acetate content of 4%. Special, soluble PVC-acetate copolymers with an average vinyl acetate content of 12%, as well as some dispersion and blending resins with a lower vinyl acetate content, are used for coatings and adhesives. 900 Chemical Economics Handbook - SRI International December 1979 POLYVINYL CHLORIDE RESINS Plastics and Resins 580.1882 B Other vinyl chloride copolymers are specialty resins of comparatively small commercial volume. Copolymers with vinylidene chloride are used in coating applications because of their enhanced solubility, and as extender resins in plastisols where rapid fusion is required. Copolymers with maleate and fumarate esters are used for special applications in coatings and adhesives. Specialty terpolymers that are used in the form of emulsions are based on vinyl acetate, ethylene, and vinyl chloride. Post-chlorinated PVC homopolymer resins are also a small-volume specialty. Products made from them have better heat resistance than products made from ordinary PVC resins. The main application is in residential hot water pipe. Minor amounts of PVC are produced and consumed in latex form (usually containing 50% solids and characterized by small particle size and low viscosity in the uncompounded state); most are homopolymers, but some are copolymers, e.g., with acrylates. MANUFACTURING PROCESSES Vinyl Chloride The bulk of the vinyl chloride produced in the United States is made from ethylene - about half by oxychlorination and half by chlorination. In both processes, ethylene dichloride is first obtained, then cracked to vinyl chloride monomer and hydrogen chloride (HC1). (In the oxychlorination process, HC1 is recycled to the oxychlorination reactor). Polyvinyl Chloride Resins Vinyl chloride, a gas at room temperature, is used in liquid form under pressure when it is polymerized by one of the four basic processes - suspension, emulsion, bulk, and solution polymerization - described in the following paragraphs. A. Polymerization Processes* In all processes, the polymerization is initiated by free radicals (produced by the thermal decomposition of such initiators as peroxides or persulfates) and proceeds at temperatures of 40-70 C with the evolution of heat. The rate of polymerization is particularly sensitive to the reaction temperature and the concentration and type of initiators used. The molecular weight distribution of the final product, which is of key importance to the processing characteristics of the resin, is also influenced substantially by these parameters. The trend in these batch processes has been toward larger and larger reactors that typically have a capacity in the range of 2,000 to 7,500 gallons, although recently reactors with capacities of 26,000 and even 35,000 gallons have been installed. In the Federal Republic of Germany, the polymerization of vinyl chloride is carried out continuously in tall reaction towers by some producers. Comprehensive descriptions and analyses of PVC manufacturing processes are provided by the Process Economics Program, SRI International. For a useful summary of PVC resin manufacturing processes and related aspects, see "Chemistry and Technology of Polyvinyl Chloride," by Roy T. Gottesman, a paper presented at the symposium of The American Chemical Society, Division of Organic Coatings and Plastics Chemistry, Atlantic City, NJ, September 11, 1974. Chemical Economics Handbook - SRI International December 1979 POLYVINYL CHLORIDE RESINS Plastics and Resins 580.1882 C The control of vinyl chloride monomer escaping into the atmosphere during its handling in the production of PVC resins and the protection of workers from exposure to vinyl chloride, e.g., during the cleaning of reactors, became an issue of great impact when, in early 1974, cases of angiosarcoma, a rare type of cancer of the liver, were first reported to have occurred among workers exposed to the monomer. Since that time, manufacturing processes have been modified to comply with stringent standards set by various government agencies to ensure uniform controls on vinyl chloride monomer, e.g., its emission, the exposure of workers, and residual content in PVC resins. 1. Suspension Polymerization. The majority of all PVC resins (both homopolymers and copolymers) produced in the United States in recent years have been made by suspension polymerization. The polymerization is carried out in an aqueous system in which monomer droplets are maintained in suspension by means of a protective colloid in conjunction with brisk agitation. Typical protective colloids are polyvinyl alcohol, gelatin, and substituted celluloses (e.g., hydroxypropyl methylcellulose). Generally, suspension polymerization is operated as a batch process employing glasslined or stainless steel reactors. The reactor is first charged with deionized water; then a protective colloid (0.05-2% of the weight of the monomer), a buffer (e.g., sodium acetate), and an initiator (e.g., lauryl peroxide, azobisisobutyronitrile, or diisopropyl peroxydicarbonate) are added. The vinyl chloride and, in the case of copolymer production, the second monomer (e.g., vinyl acetate, propylene, or vinylidene chloride) are then intermittently introduced in controlled ratios. The mixture is brought to the polymerization temperature (about 50C), and after variable induction periods depending on the initiator used, the polymerization starts. The heat of polymerization is removed from the system to maintain the desired reaction temperature. When lauryl peroxide is used as the initiator, polymerization is substantially complete after a period of about 16 hours; with diisopropyl peroxydicarbonate, typical reaction periods are on the order of 8 hours. In the last several years the use of so-called co-initiator systems, which permit better control of the molecular weight distribution and faster reaction rates resulting in higher output, has come into prominence in PVC resin production by the suspension process. Residence times of about six hours are achieved with such systems (e.g., diisopropyl peroxydicarbonate combined with acetyl cyclohexyl sulfonylperoxide). A dispersion of relatively large polymer particles in water is obtained by the suspension polymerization process. After unreacted monomer is driven out of the slurry and recovered, the slurry is centrifuged and the polymer is flash dried in an air stream at about 80C. The dry polymer is screened, generally through a 40-mesh screen, and shipped in bulk or packed in multiwall paper bags. A typical cost breakdown for suspension-polymerized PVC is as follows. CENTS PER POUND Vinyl Chloride Monomer (1.025 pounds per 1.0 pound of resin) Conversion and Overhead Depreciation Distribution Corporate Overhead Total Cost 4.7 2.7 1.5 Z.9 29.4 a. At a vinyl chloride monomer cost of 17.2 cents per pound, SOURCE: CEH estimates. Chemical Economics Handbook - SRI International December 1979 POLYVINYL CHLORIDE RESINS Plastics and Resins 580.1882 D 2. Emulsion Polymerization. Roughly 10% of the PVC resins produced in the United States in recent years was made by emulsion polymerization; this process is basically similar to the suspension process except that relatively large amounts of emulsifying agents are used, usually in pairs; one of the pair is soluble in the monomer and the other in water. Such systems effectively prevent the coalescence of polymer particles and result in resins of a very small particle size. The initiator systems used are also different from those described for suspension polymerization; typically they are redox-type systems employing persulfates. The drying methods are also designed to maintain a small particle size; spray dryers are frequently used. Because complete removal of emulsifiers is never achieved, articles of high clarity (as needed in packaging film) or of very low water absorption (as needed in wire insulation) cannot be produced from these resins. The generally higher price of emulsion-polymerized resins compared to that of suspen sion-polymerized resins is, nevertheless, accepted by users who need compounds in liquid form (fluid dispersions of PVC resins in plasticizers, called plastisols). In the United States, most resins produced by emulsion polymerization are used for plastisols (and are to a minor extent in latex form). In Europe, general-purpose resins (useful for calendering and extrusion) are also produced by variations of the emulsion process. 3. Bulk Polymerization. In this process, used to a small extent in the United States, vinyl chloride is polymerized without the addition of other liquids. A two-stage version of the process, which was developed by Pechiney-Saint-Gobain of France, has been widely licensed. U.S. licensees are Occidental Petroleum Corporation, Hooker Chemical Corporation, subsidiary; The Goodyear Tire & Rubber Company, Chemical Division; The BFGoodrich Company, BFGoodrich Chemical Division; and Certain-Teed Corporation. In the two-stage bulk polymerization process, a suitably shaped reactor is provided for the initial liquid phase of the reaction. A differently designed autoclave is used for the second phase to agitate the then-dry powdery mass effectively until the conversion from monomer to polymer reaches a level of about 80%. Heat exchange is provided by the distillation of monomer and its recondensation within the reactor and in external condensers. The rate of output in two-stage bulk polymerization plants is said to be considerably higher than that in typical suspension process plants of comparable size (i.e., with a comparable number and size of reactors). Bulk polymerized PVC resins resemble suspension resins in appearance and are charac terized by high particle uniformity and purity. These properties result in end products of unusually good optical clarity (important for packaging uses). These resins also have very good heat stability and improved fusion properties, i.e., they can be processed with the ease of conventional vinyl chloride-vinyl acetate copolymers. 4. Solution Polymerization. In this process the monomers are first dissolved in an organic solvent (such as n-butane or cyclohexane) in an autoclave. After the addition of a peroxide initiator and heating of the stirred solution to 40 C, polymerization begins and the polymer precipitates as the reaction proceeds. Solution polymerization is used exclusively for the production of specialty copolymers of vinyl chloride with vinyl acetate (usually those containing 10-25% acetate). These solution-polymerized copolymers are very pure and uniform, and their chief value lies in their unique solubility and film-forming characteristics. Chemical Economics Handbook - SRI International December 1979 POLYVINYL CHLORIDE RESINS Plastics and Resins 580.1882 E B. Compounding of PVC Resins PVC resins are compounded with a number of auxiliary materials before they are converted to end products. In the case of flexible or plasticized PVC products, the chemical types and exact amounts of plasticizers used are most important - the amount may range from about 10% (for semirigid sheet) to 100% (for very soft film) of the weight of the resin. The plasticizers are chiefly higher alcohol esters of phthalic acid (e.g., dioctyl phthalate). Polyester plasticizers (e.g., adipic acid-glycol polyesters) and epoxy plasticizers (e.g., epoxidized soybean oil) are resistant to leaching and are therefore used in biomedical products. (See the CEH Marketing Research Report on Plasticizers for detailed information). Other important compounding ingredients are light stabilizers and heat stabilizers. Among the most frequently used are heavy metal salts (e.g., of lead, tin, barium-zinc) or organotin compounds; about 0.1% to 2% (depending on the type and the fabricating process used) is added.* Pigments and fillers are incorporated, depending on the end use. When flexibility and toughness are needed in an end product, vinyl compounds tolerate only relatively light filler loadings. PVC compounding in general begins with premixing followed by very intense mixing, because uniform distribution (especially of stabilizers) is mandatory for trouble-free processing and uniform product quality. Of the many types of PVC compounds in use, most (plasticized as well as unplasticized) are relatively dry in the premix stage and have a free-flowing, sandy consistency. To achieve intimate mixing, they are subjected to a hot mixing step at fusing temperature, usually in a Banbury mixer. Modem twin-screw extruders perform these steps successively. In the case of plastisols, compounding is strictly a stir-in process (except that pigments are predispersed with plasticizer over a three-roll paint mill). Organosols (which are PVC resin dispersions in plasticizers and a balanced mixture of solvents and diluents) are usually prepared in enclosed ball mills. C. Processing of Compounded PVC Resins into End Products PVC compounds are converted to end products by several processes. Extrusion is used to produce both rigid items (e.g., pipe and conduit, siding, window sash) and flexible items (e.g., electrical wire insulation, garden hose, packaging film). Extruder trains naturally vary greatly in their particular engineering features and are designed for the production of one particular type of extrusion. Typically, extruders are continuously fed with compound, which is either purchased or prepared in an on-site compounding plant. Calendering is used for the manufacture of some types of vinyl flooring and for most of the great variety of PVC film and sheeting produced - flexible and rigid. The sheet may be combined with a fabric as it leaves the calender, or this may be done subsequently in a separate laminating step. The following book is recommended for supplemental reading on vinyl stabilizers, in particular, and vinyl compounding, in general: Harold A. Sarvetnick, Polyvinyl Chloride, Van Nostrand Reinhold Co., New York, 1969. 24855008 Chemical Economics Handbook - SRI International December 1979 POLYVINYL CHLORIDE RESINS Plastics and Resins 580.1882 F Modern PVC calenders run widths usually to 72 inches and some as broad as 92 inches. They produce film and sheet at rates averaging more than 8 million pounds per year of compound (equivalent to 5.5-6 million pounds of resin), depending on thickness (e.g., 2.5 million pounds per year for light gauge rigid film, 4.5 million pounds per year for heavier flexible film, and higher rates for flexible sheeting). Dispersions or plastisols are used mostly for fabric coating (either on knife machines, roll coaters, or casting machines) and in the production of coated types of vinyl flooring where plastisol is cast on a felt base. Plastisols are also used in rotational molding, and in dipping and hot-spraying. Compression molding of PVC resins is restricted to the production of phonograph records, although modified compression molding is used in the production of certain plasticized PVC products, e.g., automobile floor mats. Injection molding of rigid (as well as plasticized) PVC compounds was developed largely in the 1960s and is mostly employed in the production of pipe fittings. Other uses include the production of parts for automobiles, communications equipment, business machines, and toys. Blow molding requires special equipment and is used in the production of PVC bottles.

Industry sources variously apply a factor of 1.025 or 1.03 to pounds of PVC homopolymer resin produced to determine pounds of vinyl chloride monomer consumed. Using a factor of 1.025, the 1978 consumption of VCM breaks down as follows. Millions of Pounds Thousands of Metric Tons PVC Resins Exports Other Uses 5,965 899 100 2,706 408 45 Total 6,964 3,159 SOURCE: CEH estimates. The 100 million pounds for "Other Uses" represent a rough estimate of VCM used for vinylidene chloride copolymer containing less than 50% vinyl chloride, and other uses as a comonomer. Polyvinyl Chloride Resins Total consumption of PVC resins (exports included) in 1978 was 5.8 billion pounds, and it is expected to reach 6.1-6.2 billion pounds in 1979. All PVC resins are used in the production of plastic products and, to a relatively minor extent, in coatings. These PVC products are produced by a large number of fabricators, either from purchased PVC compounds (most merchant compounds are produced by PVC resin manufacturers in large, automated plants) or from compounds that the fabricators prepare themselves. In most cases, processing of the PVC compounds to the end products requires specially designed and capital-intensive operations.* This fact, and the very competitive nature of the PVC plastics business in most of its segments, explain the specialization by process of most PVC plastic producers. Rigid and semirigid (substantially unplasticized) PVC resin consumption is estimated to have totaled 3,050 million pounds (55%) in 1978, versus 2,520 million pounds (45%) for flexible (plasticized) products. Resin consumption for rigid applications has increased steadily over the last decade, primarily as a result of the continuous rise in PVC pipe production, the predominant rigid Detailed information on PVC compounding and processing may be found in the following sources: C.

Chemical Economics Handbook - SRI International December 1979 POLYVINYL CHLORIDE RESINS Plastics and Resins 580.1882 S PVC product. Other rigid extrusion has consumed much smaller, although increasing, amounts of PVC. Rigid calendering, the rigid portion of injection molding, compressionmolded sound records, blow molding, and solution coatings are the remaining rigid PVC categories. Flexible (plasticized) PVC consumption is mostly for calendered as well as dispersion coated fabrics, film and sheeting, and for extruded and injection-molded products. Per capita PVC consumption in some Western European countries, particularly in the Federal Republic of Germany, is considerably greater than in the United States. A major portion of this higher PVC usage is in rigid building products. European PVC consumption in transportation is also proportionately greater than in the United States. Total PVC consumption in Western Europe in 1978 is estimated to have been approximately 3.5 million metric tons (7.7 billion pounds), and Japanese PVC consumption was approximately one-third as large. For additional information on world PVC supply and demand and a breakdown of PVC production capacities by country, see the INTERNATIONAL section of this report. In the following subsections of this report, domestic PVC consumption is first analyzed by conversion process, and then is discussed by major end-use market. A. PVC Resin Consumption by Process of Conversion Estimated domestic PVC resin consumption by process of conversion is shown in the following table.

(C) Year-End Monthly or Annual Statistical Reports, Plastic and Resin Materials, The Committee on Resin Statistics of The Society of the Plastics Industry, Inc., as compiled by Ernst & Ernst (data for 19721978). The data show that the principal factor that drove PVC resin consumption in extrusion to current levels was pipe extrusion. a. Rigid Extrusions. The PVC resins most commonly used in rigid extrusions are suspension homopolymers of high bulk density, compounded in the form of so-called powder blends. (Postchlorinated homopolymers are also used in relatively small fO Chemical Economics Handbook - SRI International December 1979 POLYVINYL CHLORIDE RESINS Plastics and Resins 580.1882 X quantities). The resins and additives are blended to balance the required physical properties of the end product with ease and speed of processing. Aside from heat stabilizers, light stabilizers (for such products as siding), lubricants, and relatively small amounts of pigments,* impact modifiers (special acrylic and ABS polymers) are important. The bulk of PVC resin consumption in rigid extrusion is for pipe. Leading suppliers of PVC resins for pipe extrusion are listed in the table on p. 580.1882 Q. Most of these suppliers also offer powder blend compounds for pipe production. Extruded rigid PVC film and sheet** (using an estimated 35 million pounds of resin in 1978) were mostly for packaging (shrink and blister), for signs and display uses, and stationery supplies. Other rigid extrusions (using about 200 million pounds of resin in 1978) include mostly siding and window hardware. More information about each of these markets can be found in the appropriate end-use sections of this report. b. Flexible Extrusions. Approximately one-half of an estimated 850 million pounds of PVC resins consumed in flexible extrusions in 1978 (almost all general-purpose homopolymer resins) was used for wire and cable insulation (420 million pounds). The largest single product after wire and cable is clear film for meat packaging and stretch film (using about 240 million pounds of resin in 1978); other flexible extrusions include biomedical products, garden hose and other tubing, gaskets, some products used in construction, e.g., cove base, and a variety of specialty products that consume comparatively small amounts of resin. (See the Consumption By End Use section of this report for more information.) ./ f ( * See the CEH Marketing Research Report on TITANIUM DIOXIDE PIGMENTS for the consumption of that major pigment in rigid PVC extrusions. ** The term "film" is usually used for thicknesses under 6 mils (0.006 inch), whereas the term "sheet" applies to thicknesses greater than 6 mils. A good portion of so-called rigid PVC film and sheet is not strictly plasticizer-free but may contain up to 10% plasticizer, depending an the exact physical requirements in the end application.

Year-End Monthly or Annual Statistical Reports, Plastic and Resin Materials, The Committee on Resin Statistics of The Society of the Plastics Industry, Inc., as compiled by Ernst & Ernst (data for 19721978). (C) CEH estimates (all other data in the table). Most PVC calendering (using an estimated toteil of 890 million pounds of resin in 1978) involves flexible film and sheeting of a great variety but substantially all based on generalpurpose homopolymers. The use of general-purpose copolymers (with relatively high molecular weight and low vinyl acetate content) has declined since less expensive homopoly mers with comparable ease of processing have been available for a number of years. Flexible calendered film and sheeting is used in many applications; the major markets are seating for furniture and for motor vehicles; in this use, the film is combined with a backing textile, either directly at the calender or in a separate laminating step. Most of the flexible calendered film and sheeting produced is combined with textiles to produce vinyl coated fabrics; the rest is used as so-called unsupported film and sheeting. PVC coated fabrics and film and sheeting are vised in many other markets, mostly for home furnishings and consumer goods. Production of calendered film, sheet, and coated fabrics recovered in 1978 after a decline in 1977 when a flood of imported calendered goods from the Far East appeared on the U.S. market (for such uses as outerwear, footwear, handbags, inflatable toys, and other consumer goods). PVC resin consumption in calendered flooring in 1978 was about 170 million pounds. Of this amount, an estimated 70 million pounds were for vinyl-asbestos floor tile, and the balance was for plasticized roll goods. Rigid calendering consumed an estimated 90 million pounds of specialty resins, some of them copolymers. The principal end uses for calendered rigid PVC sheet sure in packaging. There are probably about 130 PVC calenders in operation in the United States, most of them producing flexible film and sheeting, and flooring. The largest calender operators for general PVC film and sheet production include the following companies (listed in order of estimated production capacity and output). 6T0SS8fc Chemical Economics Handbook - SRI International December 1979 POLYVINYL CHLORIDE RESINS Plastics and Resins 580.1883 B The General Tire & Rubber Company Kalex Chemical Products, Inc.

(B) Synthetic Organic Chemicals, U.S. Production and Sales, U.S. Tariff Commission (FLOORING and PLASTISOL FORMULATING AND MOLDING data for 19621971; TEXTILE AND PAPER COATING data for 19661971). (C) Year-End Monthly or Annual Statistical Reports, Plas tic and Resin Materials, The Committee on Resin Statistics of The Society of the Plastics Industry, Inc., as compiled by Ernst & Ernst (all data for 1972-1978). An additional amount of so-called blending resin is consumed in these dispersions; typically, 80 parts of dispersion resin are blended with 20 parts of the (less expensive) blending resin. However, blending resins are not used in all applications of dispersion resins. Overall, a factor of 1.15 applied to dispersion resin consumption provides a useful approximation for the total resin consumption that includes blending resins. A large part of the growth of dispersion resin consumption in the 1970s is attributable to the commercial success of coated types of vinyl flooring. (Major producers are listed on p. 580.1883 P). Also, the production of plastisol-coated fabrics* for use in automobiles, furniture, garments, luggage, wall coverings, and a multitude of other items has shown consistent growth despite competition from calender-coated textiles. Most large coaters operate both calender and dispersion processes because technical factors usually dictate the use of one process or the other for a particular product. Processes include knife coating, reverse roll coating, casting (used for coated fabrics), rotational or slush molding (to make hollow objects such as beach balls), dipping (for gloves and tool handles), and hot spraying (thick protective coatings on metal objects such as tool housings). Casting ovens came into widespread use in the 1960s. Typically, a PVC dispersion is cast on release paper that may be embossed; it is fused, separated from the substrate, and in most cases, combined with a textile. Sometimes chemical blowing agents are employed to produce a cellular structure. Major producers of dispersion-coated fabrics include Borden Inc., The General Tire & Rubber Company, Pervel Industries (division of Bemis Company, Inc.), the BandelBradford Company, and Uniroyal, Inc. Most PVC dispersion resins are homopolymers, but some copolymers are used (most are prepared by the emulsion process). Blending resins (used in conjunction with dispersion resins to lower the cost and to adjust flow properties) are also mostly homopolymers, but they are produced by the suspension process. Nonwoven webs, papers, and saturated felts are used as a substrate for specialty products. Chemical Economics Handbook - SRI International SO 15 1 07 o so December 1979 POLYVINYL CHLORIDE RESINS Plastics and Resins 580.1883 F In 1978, approximately 530 million pounds of dispersion resins are estimated to have been used in conjunction with about 85 million pounds of blending resins. In addition, a major portion of an estimated 70 million pounds of PVC latexes (resin content) consumed were used in conjunction with dispersion coating operations. This total consumption can be broken down as follows.

A major portion of the resin used for molding, dipping, for protective coatings, and smaller portions of some of the other categories went through formulator/compounders. Included in the coated fabrics category is the use of plastisols as tie-coats for laminating film to fabrics or other substrates; also included are nonwoven fabrics, in which some latex may be involved. Some of this consumption may be reported by the SPI under "Adhesives and All Other Coating Uses." (See p. 580.1883 T of this report). Molding is mostly rotational molding and slush molding of hollow articles that include toys and novelties, recreational articles (such as beach balls, bicycle saddles, basket balls), a few automotive interior trim items (some headrests, armrests, and crash pad skins), and other specialty products.

Compression Molding. The principal component is the reported consumption of resins for phonograph records, which require special acetate copolymer resins. This resin consumption for phonograph records has always been a separate reporting category, but other compression molding is believed reported together with other consumption under "All Other Molding." Strictly speaking, there is no compression molding of PVC other than sound records, but there is resin consumption for some press-molded articles that are plasticized. Although very low pressure is involved in the molding of, for example, automobile vinyl floor mats, or kitchen drainboards (in most cases the compound is injected into the mold), some of this production can be called compression molding. b. Injection Molding. The principal component is consumption for pipe fittings. Injection molding of PVC resin for rigid and plasticized products other than pipe fittings is estimated to have consumed 210 million pounds of resin in 1978. Typical products (in addition to those mentioned under Compression Molding) include electri cal outlet boxes (rigid), electrical outlet plugs, filler strips and other parts for automobile bumpers, automobile rearview mirror housings, window winder knobs, bicycle grips, toys, shoe soles and heels (unit soles), and a variety of parts for business machines and electrical and electronic uses. Typically, injection molders buy pelletized compound. PVC compounds for injection molding are made and sold by such companies as BFGoodrich, Schulman Manufactur ing, and Firestone Plastics. c. Blow Molding. This sophisticated technology was developed in the 1960s and is used for the production of containers. The bulk of the polymer used is high-density polyethylene; PVC consumption is relatively small and is mostly for bottles of chemicals and pharmaceuticals.

Data on PVC resin consumption in coatings and adhesives in recent years are given in the following table.

Chemical Economics Handbook - SRI International D'ecember 1979 POLYVINYL CHLORIDE RESINS Plastics and Resins 580.1883 K This consumption has been reported as "Protective Coatings and Adhesives" and recently was in a category called "Adhesives and All Other Coating Uses." A major portion of this consumption has been in applications in which the resin is dissolved (about 90 million pounds in 1978); dispersion resins, powder coating resins, and latex probably account for most of the balance; Solution-grade resins are produced mostly by solution polymerization (Union Carbide), and most are vinyl chloride-vinyl acetate copolymers with vinyl acetate content of 81Z%. One type often used in adhesives is modified to contain a certain amount of free carboxyl groups, and another type frequently used in protective coatings contains free hydroxyl groups. Other acetate copolymers are used, often in admixture with acrylic resins, for rotogravure printing inks and topcoatings on vinyl film and sheeting. Can coatings and other packaging applications are also important markets. Adhesives based on or containing PVC copolymer resins are used in a variety of specialized industrial applications. Typical solvents used in the solutions are cyclohexa none, tetrahydrofuran, methyl ethyl ketone, and diisobutyl ketone; however, some of the resins tolerate the presence of minor quantities of aromatic hydrocarbon diluents. (For more information on the use of PVC resins in coatings, see the CEH Marketing Research Report on VINYL SURFACE COATINGS). Resin consumption for PVC powder coatings does not amount to more than 5 million pounds per year. Chemical Economics Handbook - SRI International December 1979 POLYVINYL CHLORIDE RESINS Plastics and Resins 580.1883 L 6. All Other Uses. This category accounts mostly for resins sold to distributors and to compounders with an end use undetermined when the resin is sold. The category serves largely to balance statistics (i.e., the bulk reported under this heading actually belongs in the individual process category previously discussed). The following table presents the reported data with pertinent commentary in the footnotes.

The actual figures reported for I960 and 1961 were 113 million pounds (51 thousand metric tons) and 125 million pounds (57 thousand metric tons), respectively. An estimated 30 million pounds (14 thousand metric tons) of resins used in commercial plastisols were subtracted in each year and added to the table on U.S. consumption of PVC dispersion resins (pp. 580.1883 C-D). b. The 161 million pounds (73 thousand metric tons) reported by the source include an estimated 40 million pounds (18 thousand metric tons) of exports (included in the U.S. TRADE section of this report). c.

PVC resin consumption in some specialty uses may not have been covered by the main process categories. B. Consumption by End Use A breakdown of domestic PVC resin consumption by major market category is given in the following table. ESTIMATED DOMESTIC CONSUMPTION OF PVC RESINS - 1978 Millions of Thousands of Pounds Metric Tons Construction Consumer Goods Electrical Uses Packaging Transportation Home Furnishings Miscellaneous Uses 3,000 710 510 460 280 220 390 1,361 322 231 209 127 100 177 Total 5,570 2,527 SOURCE: CEH estimates. The individual categories are discussed in the following paragraphs. Chemical Economics Handbook - SRI International December 1979 POLYVINYL CHLORIDE RESINS Plastics and Resins 580.1883 N 1. Construction. Estimated PVC resin consumption in construction is listed below. ESTIMATED CONSUMPTION OF PVC IN CONSTRUCTION - 1978 Millions of Thousands of Pounds Metric Tons Pipe and Conduit Pipe Fittings Siding, Window Hardware, and Other Rigid Profiles Flooring Wall Coverings and Paneling Pool and Pond Lining Other 2,160 120 200 375 80 30 35 980 54 91 170 36 14 16 Total 3,000 1,361 SOURCE: CEH estimates. Pipe, Conduit, and Pipe Fittings. The data in the preceding table indicate that 39% of the total PVC resin consumption is for pipe, conduit, and pipe fittings. The data represent PVC resin shipped to pipe producers, not actual pipe shipped or installed. Massive federal funding of rural water projects and HUD support of plastic pipe use in the early 1970s were principal factors in the phenomenal growth of PVC pipe markets in the last decade. It is estimated that PVC has 70-80% of the current total plastic pipe and conduit business on a poundage basis. A breakdown of the PVC pipe and conduit market is as follows. ESTIMATED PVC CONSUMPTION IN PIPE AND CONDUIT - 1978 Millions of Thousands of Pounds Metric Tans Water-Supply Pipe Sewer and Drain Pipe Electrical and Telephone Conduit Drain, Waste, and Vent Pipe Agricultural and Turf Irrigation Other Pipe 740 350 310 250 200 120 336 159 141 113 91 54 Total 1,970 894 SOURCE: CEH estimates. These data represent the PVC content of (salable) pipe shipped. The PVC resin content of pipe and conduit varies from about 80% for some types of conduit to 95% or more for most pressure pipe, overall, the resin content can be considered to be about 90% by weight. Chemical Economics Handbook - SRI International December 1979 POLYVINYL CHLORIDE RESINS Plastics and Resins 580.1883 O The penetration of pipe markets by plastic pipe (on the basis of economics and performance properties) varies greatly. For water-supply pipe the penetration is estimated to be less than 50% overall, and considerable growth potential for PVC is seen in the municipal water pipe market. However, the fastest growing segment for PVC pipe in the 'last three years has been sewer pipe, which is expected to lead future demand growth for PVC pipe. Resin consumption for conduit (which includes conduit for power cables and electrical wiring, and for communication wiring) also has increased markedly in the last few years. The drain, waste, and vent (DWV) segment, which PVC shares with ABS at a roughly 50:50 ratio, is more than 50% penetrated and has shown relatively little demand increase for PVC in the recent past. Similarly, at least 50% of the agricultural and turf irrigation pipe is believed to be plastic (with PVC the predominant plastic pipe used). Other pipe markets of commercial significance include natural gas distribution pipe (predominantly polyethylene), with an estimated penetration by plastic of 40-50%, water distribution (inside the house, with minimal penetration by plastic), oil production pipe, and chemical process pipe (for which plastics are heavily used). The leading multiplant producers of PVC pipe and conduit include the following companies (listed by estimated pipe extrusion capacity and output). Robintech Incorporated Johns-Manville Corporation Certain-Teed Corporation Indian Head, Inc., Carlon Division Harsco Corporation, Cantex Division Robintech is believed to process 300-400 million pounds of PVC pipe resin annually. Other smaller extruders of PVC pipe include Gifford-Hill & Company, Inc., Western Plastics Corporation (Tacoma), Celanese Piping Systems Division of Celanese Corpo ration, and Clow Corporation. There is also a large number of smaller single-plant producers.* R. & G. Sloane Manufacturing Company, Inc., is the leading producer of fittings for PVC pipe and conduit. b. Siding, Window Hardware, and Other Rigid Profiles. The major portion of this consumption, an estimated 150 million pounds in 1978, is for siding. PVC siding is now cost-competitive with aluminum siding. That, as well as quality improvements, have resulted in strong demand for PVC siding in 1978 and 1979. Distributors of aluminum siding now typically carry a complete line of PVC siding as well; Alcoa has become a producer of PVC siding (major producers of PVC siding are Bird & Son, Inc., Certain-Teed Corporation, and Mastic Corporation). In the past, most PVC siding was sold in the replacement (remodeling) market and for mobile homes, but recently its use in new residential construction has become more widespread. An estimated 45 million pounds of PVC were used for windows and window hardware in 1978. PVC consumption in window frames is still mostly for vinyl-clad wood; vinyl is extruded directly over a wood core of the sash, while corner joints are given a welded Listings of all producers of approved PVC and other pipe are in the directory of the National Sanitation Foundation Testing Laboratory, Inc., Ann Arbor, Michigan. Chemical Economics Handbook - SRI International December 1979 POLYVINYL CHLORIDE RESINS Plastics and Resins 580.1883 P seal after assembly. In another method, rigid PVC extrusions are attached to wooden frames with adhesives. All-vinyl windows are still at the infancy stage. Rigid profiles other than window frames are spline for storm windows and doors, rigid weather stripping, and molding. Some gutter and rigid profile sheet are also included in this market segment, as are shutters thermoformed from extruded sheet. c. Flooring. Coated PVC flooring (typically with a saturated felt base and intermediate layers that are sometimes cellular in structure) is still the leading product category and is estimated to have consumed 210 million pounds of dispersion and blending resins in 1978. Calendered vinyl flooring has been holding its position (these products are typically calendered with copolymer resins that are highly filled); the 1978 resin use is estimated at about 170 million pounds. Leading producers of vinyl flooring include the following companies. Armstrong Cork Company Congoleum Industries Inc. GAF Corporation Kentile Floors Inc. Mannington Mills Inc. National Floor Products Company, Inc. Vinyl Plastics Inc. In contrast to the declining vinyl flooring market of the 1960s, the industry has been characterized by growth since that time as a result of attractive new products. The large replacement market is believed to be growing more than the new construction market as the remolding of older homes gains importance in the face of soaring building costs. d. Other Uses in Building and Construction. PVC wall coverings (actually a consumer product in the sense that they are in the replacement market as much as in new construction) are mostly coated fabrics (predominantly sheetings and sateens) with film thickness of 5-20 mils; some constructions use nonwoven webs as a substrate. An estimated 55 million pounds of PVC were used for these products in 1978. About two-thirds are calendered, the balance dispersion coated. In addition, there is paneling, consisting of particle board or gypsum board to which a rigid or flexible vinyl film (typically painted with a wood-grain pattern) is laminated. In 1978, an estimated 25 million pounds of PVC went into these products, which are not all used for wall paneling but are also used for furniture and other case goods such as speaker cabinets and for the interiors of recreational vehicles. Also included in this category is PVC sheet for swimming pool liners and for the lining of water settling ponds and reservoirs. Other inclusions are resins used for some extruded products such as cove base and for some rigid PVC products used in industrial ducting and fan impellers and housings. Chemical Economics Handbook - SRI International December 1979 POLYVINYL CHLORIDE RESINS Plastics and Resins 580.1883 Q 2. Consumer Goods. This large market is highly diversified. An attempted breakdown is given in the table below. ESTIMATED CONSUMPTION OF PVC RESIN IN CONSUMER GOODS - 1978 Millions of Thousands of Pounds Metric Tons Sound Records Footwear, Handbags, Purses, and Similar Articles; Bookbinding; Toys and Recreational Articles; Kitchenware and Appliances; Consumer Electronics; Luggage; Garden Hose Other (e.g., beauty supplies, novelties, stationery articles, window shades, waterbeds, tool handles, bicycle grips, wigs, plastic Christmas trees) 210 400 100 95 181 45 Total 710 322a a. Total does not equal sum of categories due to rounding. SOURCES: CEH estimates. The largest single segment, sound records, requires special polyvinyl chloride-acetate copolymers for compression molding. This market was rather static for a long time, but it surged in 1978 as a result of several events (among them the death of singer Elvis Presley and also as a result of severed highly successful new releases). While the level of resin use for records dropped in 1979, industry observers expect a pattern of fluctuating demand around the 200 million pound-per-year level in the next few years. In spite of skyrocketing costs for recordings, new pressing facilities are in the installation and planning stage. The next largest single market of this category is probably footwear, which includes coated fabrics (for uppers and linings), calendered or extruded soling, and injectionmolded soles and heels for sneakers and other shoewear. Also included are injectionmolded boots. PVC resin use for this market is believed to total somewhat over 100 million pounds, but it fluctuates from year to year depending on fashion trends. Also included are coated fabrics and film and sheeting for such diverse uses as handbags and purses, toys and recreational articles (mostly cases or bags, e.g., for golf clubs, rifles, backpacks, and camping gear), for luggage, kitchenware and appliances (gaskets), and garden hose. Chemical Economics Handbook - SRI International December 1979 POLYVINYL CHLORIDE RESINS Plastics and Resins 580.1883 R 3. Electrical Uses. Total PVC consumption in 1978 for electrical uses is estimated to have been 510 million pounds. Wire and cable insulation, the predominant use, consumed 420 million pounds. This market can be subdivided roughly as follows. ESTIMATED BREAKDOWN OF PVC CONSUMPTION IN WIRE AND CABLE - 1978 Building Wire and Power Cables Communication and Signal Wire Flexible Cord (for household lamps, extension cords) Automotive Electrical Wire and Other Auto Uses Appliance Wire Total 50% 20 12 10 _____8_ 100% SOURCE: Communication with industry. PVC shares the wire and cable market with several other plastics and elastomers. Polyolefins are better electrical insulators, but PVC is a better jacketing material when resistance to flexing is required in a wire or cable. The largest use of PVC in wire and cable is in the low-voltage field (500V and below), in which building wire accounts for a large portion. PVC jacketing, usually black, is common on 1-5 kV unshielded distribution cable for industrial use and in low-voltage city networks, as well as on cables for the 10-35 kV range that are used by utilities in underground power distribution. PVC resins used for wire and cable are of slightly higher molecular weight than calender-grade resins but are sold as general-purpose resins. Wire and cable extruders use large amounts of compound (pelletized) as well as resin (for their own compound ing). The largest suppliers of PVC compounds for wire and cable are BFGoodrich, Firestone, and Tenneco. The largest wire and cable extruders are listed below. COMPANY PLANT LOCATION Aluminum Company of America Marshall, Texas Massena, New York The Anaconda Company Anaconda Wire & Cable Co., subsidiary Belden Corporation Marion, Indiana Orange, California Sycamore, Illinois Watkinsville, Georgia Richmond, Indiana Essex International Inc.

Other large consumers in this field include Packard Electric Division of General Motors Corporation (Warren, Ohio) and Prestolite Division of Eltra Corporation (Port Huron, Michigan, and Hazelton, Pennsylvania), both producers of automotive wire and cable products. Outside of wire and cable insulation, about 20 million pounds of PVC were used in rigid injection molding for electical outlet boxes and, to a minor extent, for some other items in the electronics field. An estimated 70 million pounds were used for outlet plugs and for wire connectors. PVC consumption for electrical tape is not included here. 4. Packaging. A breakdown of PVC resin consumption in packaging is given in the following table. ESTIMATED PVC RESIN CONSUMPTION IN PACKAGING - 1978 Millions of Thousands of Pounds Metric Tans Plasticized Clear Film Bottles Rigid Sheet (blister and trays) Coatings Closures Total 235 90 90 15 30 460 107 41 41 7 14 209a a. Total does not equal sum of categories due to rounding. SOURCE: CEH estimates. Of the extrusion-blown plasticized clear film, about 150 million pounds were for meat wrap, and the balance was mostly for stretch film. The Resinite Division of Borden Inc. 2481 028 Chemical Economics Handbook - SRI International December 1979 POLYVINYL CHLORIDE RESINS Plastics and Resins 580.1883 T is the largest producer, followed by The Goodyear Tire & Rubber Company. Rigid sheet (of which about 60 million pounds were calendered and the balance extruded) is mostly for blister-packaging and shrink-packaging of hardware; lesser quantities are used for processed meats and for pharmaceuticals, for trays or boxes for candy, and for greeting cards. An example of a food packaging film composite employing PVC is a laminate of Saran-coated polyethylene film and PVC. Also, laminates of PVC and Saran films are used. Such combinations provide both the barrier properties and processing characteris tics (e.g., for heat sealing) needed. Closures involve plasticized bottle cap and jar lid linings based on dispersion resins. Resin consumption for coatings is for can coatings. 5. Transportation. An estimated breakdown for 1978 consumption in the transportation market is given below. ESTIMATED PVC RESIN CONSUMPTION IN TRANSPORTATION - 1978 Millions of Thousands of Pounds Metric Tons Passenger Car Seating and Interior Trim (including trunk lining) Seating and Accessories for Trucks, Buses, and Other Vehicles (e.g., campers, mass transit, snowmobiles) Auto Floormats Auto Tops and Exterior Trim Bumper Strips, Bumper Guards, Window Winder Knobs, and Other Items Other Total 135 30 25 25 20 45 280 61 14 11 11 '9 20 127a a. Total does not equal sum of categories due to rounding. SOURCE: CEH estimates. Most of this consumption is in the form of coated fabrics (about three-fourths of these are calender-coated, and the balance is dispersion coated). Floor mats are molded from extruded sheet or injection molded; such items as bumper guards, window winder knobs, and rearview mirror housings are typically injection molded. The resin consumption listed under "Other" is for such items as air filter incaps, battery separators, and other items. This market has not grown for PVC, overall, in the last two years. Principal factors are the trend toward smaller cars, the increasing use of fabrics instead of vinyl for seating, and the loss of the vinyl headliner to the rigid molded snap-in headliner on most GM cars. Chemical Economics Handbook - SRI International December 1979 POLYVINYL CHLORIDE RESINS Plastics and Resins 580.1883 U 6. Home Furnishings. An estimated breakdown of this market is given in the following table. ESTIMATED CONSUMPTION OF PVC IN HOME FURNISHINGS - 1978 Millions of Thousands of Pounds Metric Tons Furniture Upholstery Shower Curtains Adhesive-Backed Film Tablecloths and Placemats 150 10 10 50 68 5 5 23 Total 220 iooa a. Total does not equal sum of categories due to rounding. SOURCE: CEH estimates. Most of the products listed are made from calender-coated fabrics and, to a lesser extent, dispersion-coated fabrics and unsupported film. Vinyl furniture upholstery, the largest single end use of this category, has declined somewhat in the last two years as upholstery fabrics have become less expensive relative to vinyl. Also, polypropylene upholstery fabrics have taken an increasing share of this market. 7. Miscellaneous Uses. A total of 390 million pounds of PVC is estimated to have been used in miscellaneous applications in 1978. About 180 million pounds of this were for coatings and adhesives. Included are an estimated 75 million pounds of resin for highperformance protective coatings (based on special copolymers) for ships, and for industrial, military, and farm equipment; and topcoatings and inks (often in admixture with acrylic resins) for coated fabrics and sheeting. Solvent-based adhesives containing these PVC copolymers in conjunction with other resins are used in the manufacture of leather goods and simulated leather goods including luggage, shoes, handbags, and purses; and in the assembly of toys, novelties, and swimming pool liners. About 35 million pounds of noncoating specialty applications of these same types of soluble resins are also included, as are resins for powder coatings (less than 5 million pounds). Some plastisols and an estimated 70 million pounds (dry basis) of latex are also included, the main use of which is for coated fabrics; some dipped products are also included. Other uses for PVC in this category are for medical tubing, blood bags, and for other hospital and health care uses; credit card stock (rigid sheet); and flooring applications such as carpet and synthetic turf backing. 24f 5039 Chemical Economics Handbook - SRI International December 1979 POLYVINYL CHLORIDE RESINS Plastics and Resins 580.1883 V PRICE AND UNIT SALES VALUE Vinyl Chloride A history of vinyl chloride prices and unit sales values is given in the following table.

Imports Data on U;S. imports of vinyl chloride are reported by the U.S. Department of Commerce, Bureau of the Census under import code # 429.4400. U.S. imports of vinyl chloride were negligible from 1964 through 1967. Since 1968, they have been less than 5 million pounds per year. The import rate of duty on vinyl chloride prior to 1968 was 2.5 cents per pound (5.5 cents per kilogram) plus 12.5% ad valorem. As a result of the Kennedy Round Agreements, the duty was decreased in stages to 1.25 cents per pound (2.8 cents per kilogram) plus 6% ad valorem as of January 1, 1972 (Tariff Schedules of the United States Annotated (1976), USITC Publication 749, U.S. International Trade Commission).
