Thermoplastics News ISSUE No. 3 GOODRICH ANNOUNCES RESULTS OF NEW VINYL CHLORIDE CONTAINMENT PROGRAMS John D. Ong, President of The B.F. Goodrich Com pany, announced the company's progress in contain ment of vinyl chloride in its plants, in the atmos phere and in PVC resin at a press briefing in New York, December 4, 1975. The results indicated the largest research and develop ment program in B.F. Goodrich's history has enabled the company to continue and expand production of polyvinyl chloride (PVC) while complying with exist ing or expected Federal regulations on vinyl chloride gas exposure. PVC is the second largest-selling plastic in the United States. Goodrich operates five PVC plants and one plant that produces the vinyl chloride (VC) monomer from which PVC is manufactured. We now believe that the chances are extremely remote of future angiosarcoma (a rare form of cancer) cases resulting from vinyl chloride exposure in our current operations. We still face the possibility that, because of the long latency period, we will see other cases of angiosarcoma among workers who experienced ex posures at high levels in the past. Masks fed by clean air virtually eliminate the pos sibility of breathing vinyl chloride gas by polyvinyl B.F. Goodrich plants. The company's PVC and vinyl chloride plants are operat ing at levels of 1 to 3 parts of vinyl chloride per mil lion parts of air (ppm) in work areas. Highly accurate personal monitoring systems mea sure amounts of vinyl chloride gas which can be breathed by workers in polyvinyl chloride (PVC) operations. These devices show that exposure of work ers to the gas is below the standard established by the Federal Occupational Safety and Health Administration. B.F. Goodrich's new poly vinyl chloride (PVC) facility at Louisville, Kentucky, will be as good or better than any plant in the country in the prevention of employee exposure to vinyl chloride gas, escape of VC to the environment, and in reducing the amount of VC in resins produced to trace amounts, according to com pany engineers. For further information on the new vinyl chloride stripping process, refer to the cover article in Thermoplastics News, Issue No. 2. Even though the containment technology we have developed is proprietary, and could give Goodrich competitive advantage, we consider it our responsibi lity to make it available on an unrestricted basis to all competitors in the PVC and vinyl chloride monomer industry in the United States and abroad. It is B.F. Goodrich's intention to continue efforts to reduce vinyl chloride exposure resulting from all operations and products, and to continue our research and development efforts to refine techniques and develop new ones.

This system allows plastic materials to be exposed to proper amounts of shear rate and heat as they passthrough the thermoplastic extrud er. By design, materials are prepared to an optimum melt quality. The result is maximum extrusion rate at minimum stock temperatures. The capability of the Kim Screw has been demonstrated at our Avon Lake Technical Center on both Estane polyurethane and Geon Dr. H. T. Kim flexible PVC materials. Examples of its capability are: Geon PVC can produce high quality tubing at rates of 275 to 300 pounds per hour. Estane 58300 is also being extruded in the United States into wire and cable jacketing at rates ranging from 60 to 100 pounds per hour on 2'A inch, 24:1 extruders. The new Kim Screw can produce high quality wire and cable jacketing on the same size ma chine, using the same material, at 275 to 325 pounds per hour and a stock temperature near 204C (400F). Estane Polyurethane Today, Estane 58300, a polyether polyurethane, and Estane 58092, a polyester polyurethane, are being extruded into tubing at rates ranging from 60 to 100 pounds per hour on 214 inch, 24:1 extruders. This new screw, using the same materials and machine. Geon 8730, a PVC wire and cable jacketing com pound, is being extruded in the United States at rates between 100 to 150 pounds per hour on 2/4 inch, 24:1 extruders. The new Kim Screw, using the same material and machine, can produce high quality tubing at rates of 250 to 300 pounds per hour -- from both powders and cubes. REBOUNDOME Rebounding, one of the most important aspects of every fastbreaking, hard fought basketball game, is one of the most difficult skills for players to acquire. Reboundome is a basketball training aid manufactured by Hayden Industries, Inc., Avon, Ohio and easily installed using mounts made of Estane thermoplastic polyurethane. These mounts are injection molded by Moore Mold and Die Company of Euclid, Ohio. The durable mounts provide the right balance of stiffness and resiliency to simulate rebounds from the hoop. The dome may be quickly and easily removed at the completion of practice. According to Hayden Industries, John R. Wooden, former coach of the UCLA Bruins, NCAA champions for 10 of the past 12 years, says that "The Reboun dome is an excel lent device for improving the effective ness of the individual rebounder." Winning coaches including Fred Taylor, Ohio State, Bob Knight, Indiana, and Joe Hall, Kentucky, make Reboundome drills part of their regular training routines, Hayden reported. 21514002 RPr.i47i^ SPRAYABLE PAINT SYSTEMS WITH HYCAR ATBN FOR RUBBER SURFACES Intercures of carboxylic elastomers, phenolic and epoxy resins are known to provide good adhesion to vulcanized rubber surfaces. Similarly, it has been found that combinations of Hycar 1300X16 ATBN, a deprimary amine liquid polymer of butadiene/ acrylonitrile, phenolic and epoxy resins, are useful as the polymeric formulating basis for paints, primers and coatings for vulcanized elastomers, thermoplastic elastomers and thermoplastic urethanes. A typical formulation is: Component A Hycar 1300X16 ATBN Titanox RA-50 (Titanium Pigment Corp.) Toluene/xylene 50/50 Toluene/xylene/MEK 50/15/70 Total 100.0 76.5 36.2 168.9 381.6 Component B DER 331 (Dow Chemical Co.) BKR-2620 (Union Carbide Corp.) Methyl ethyl ketone Toluene/xylene 50/50 Toluene/xylene/MEK 15/15/70 20.0 50.0 164.4 34.2 113.0 Total 381.6 Titanium dioxide level may be varied; other fillers (pigments) could be used or none at all. Modulus may be significantly altered by varying the phenolic resin level. Preparation: Component A is prepared by dispersing coarsely the first three ingredients with good agitation. Two passes are then made through a 3-roll ink mill (roll gaps at 2 and 1 mils) (.050 and .025 mm). In gredients listed as the fourth item are then blended in. Component B is prepared by adding ingredients one and two to the mixture of three, four and five. If a residue exists after stirring, then filter Component B to obtain a clear solution. Mix A and B well in equal proportions prior to spraying. Application: After mixing Components A and B, spray with normal paint spraying equipment. Apply no more than 1.0 to 1.5 mil (.025 to .038 mm) thicknesses and no more than three passes over the surface. Air dry (30 to 60 seconds) between coats and prior to curing. Paint systems with Hycar ATBN are normally cured for 10 to 15 minutes at 250F (121C). Properties were obtained on a system having 50 parts titanium dioxide, cured 10 minutes at 250F (121C). 3 Tensile strength, psi (MPa*) Elongation, % 10% Modulus, psi (MPa) 20% Modulus, psi (MPa) 50% Modulus, psi (MPa) 100% Modulus, psi (MPa) Gehman Freeze, C 2860 (19.7) 140 1460 (10.1) 1550 (10.7) 1850 (12.7) 2340 (16.1) -45 Adhesion to thermoplastic polyurethanes, EPDM, etc. (cross-hatch testing): Original -- no adhesion failure 7 days, 158F (70C) -- no adhesion failure 7 days, 158 F (70C) -- no adhesion failure plus 2 hrs, at 151F (66C), water Ozone Chamber Testing: 2000 hrs. at 50 and 500 ppm ozone - no signs of cracking, chipping, hardening or adhesion loss.

The dusty, cramped, truck cab has been replaced by a sophisticated control center in vehicles built by Mack Trucks, Inc., Allentown, Pennsyl vania. Drivers ride in air-conditioned comfort surrounded by panels which provide constant monitoring of engine performance. While the emphasis is on modernity and com fort, the truck cab interior must also be built to withstand years of hard wear and tear and provide efficient service for thousands of miles. Fulfilling these needs, Mack Trucks selected Abson ABS for the dispatch boxes and the housing of the air conditioning and heating air circulation inlets. The deflectors on the inlet housing are injection molded and chrome plated. The housing is vacuum formed by Brentwood Plastics, Inc., Reading, Pennsyl vania, from sheet made of Abson ABS. Easily fabricated using standard fasteners and hinges, the parts made of Abson ABS are tough and durable. According to Brentwood, the dispatch box and housing exceed the flammability requirements of Federal Motor Vehicle Safety Standard 302.
