HOMS 075842 What are the Aroclor Polychlorinated Polyphenyls These compounds are a series of chlorinated bi phenyls and chlorinated polyphenyls. They range in form and appearance from mobile oily liquids to fine white crystals and hard transparent resins. Aroclor is non-oxidizing, permanently thermo plastic, of low volatility, and non-corrosive to metals. Aroclor is not hydrolyzed by water, al kalis, or acids. The viscous liquids and resins will not support combustion when heated alone, and they impart fire-resistance to other materials. Crystalline Aroclor is relatively insoluble, but the Jiquid and resinous compounds are soluble in most of the common organic solvents, thinners and oils. All Aroclor chlorinated compounds are insoluble in water, glycerine or the glycols. Aroclor 5460 is insoluble in the lower molecular weight alcohols; 4465 is only partly soluble in the lower alcohols. Aroclor is used alone for a particular physical job, such as insulating, and as a sealant or expansion media. Aroclor is also used as a component or ex tender in elastomers, adhesives, paints, lacquers, varnishes, pigments and waxes. The properties imparted by Aroclor (and their usefulness in par ticular applications) vary in regular gradient over the series. Selection of the right Aroclor for a par ticular use can generally be made by comparison of the properties, by blending two or more, and by adjusting the percentage used in the particular mixture in which the Aroclor will be formulated. The following table describes the properties of twelve Aroclor chlorinated compounds, each of which is representative of a series. For almost every Aroclor shown, there is a dark-colored grade of approximately the same physical and chemical characteristics. These darker products are less pure, but are lower in price.

Even when exposed to air in Ihe form of thin films, no noticeable oxidation or burdening lakes place. However, when used as a component of paints, varnishes or lacquers, it does not retard the rate of drying of the films. Quick drying varnishes and paints can be made using Aroclor in the formulation. FIRE-RESISTANCE Viscous, oil-like Aroclor and the Aroclor resins do not support combustion when heated alone, even at their boiling points -- temperatures in excess of 850*C. Most of the Aroclor chlorinated com pounds flux readily with other resinous and pitch like materials to make mixtures that gain in fire rcturdance properties. Even when incorporated in nitro-cdlulose films and rubber foams, Aroclor will retard the rule of burning. ADHESIVENESS AND THERMOPLASTICITY The Aroclor resins adhere strongly to smooth surfaces such as glass, metal, varnished or lac quered coatings. Aroclor is permanently thermoplastic. It appar ently undergoes no condensation or hardening upon repeated melting and cooling. Clear Aroclor resins can be supplied with softening points up to 106'C. Opaque, crystalline Aroclor can be sup plied with initial melting points up to approxi mately 290F. STABILITY Toward Alkalies -- Aroclor ia remarkably re sistant to the action of either hydrolyzing agents or high temperature. It is not affected by boiling with sodium hydroxide solution. Toward Acids -- Experiments were made to de termine whether hydrogen chloride ia evolved dur ing the treatment of Aroclor with sulfuric acid. Aroclor 1264 (selected as typical) was stirred with an equal volume of ten per cent sulfuric acid for a period of 150 hours. Any gases escaping from the reaction fiask had to pass through a trap filled with silver nitrate solution, which would give a precipitate of silver chloride if any HC) came in contact with it. After 150 hours of treatment, neither the trap solution nor the acid layer in the treating flask showed any hydrogen chloride present. Even prolonged treatment (255 hours) with con centrated sulfuric acid indicated negligible effect. Toward Heat -- Aroclor is a useful heat transfer media because of its stability to heat. Aroclor 1254 and particularly the less viscous Aroclor 1248 are recommended for this purpose because they may be heiited at temperatures up to 315C (600F) in a closed system for long periods without appre ciable decomposition and they are fire-resistant. Toward Oxidation -- When Aroclor is subjected to a bomb test at 140C with 250 pounds oxygen per square inch, there is no evidence of oxidation as judged by development of acidity or formation of sludge. ELECTRICAL RESISTIVITY Aroclor has extremely interesting electrical charac teristics: high resistivity and dielectric strength and low power factor. The dielectric constant ranges from 3.4 to 5.0 at 100C and 1000 cycles, depending upon the particular Aroclor. SOLUBILITY All Aroclor chlorinated compounds are insoluble in water. They are soluble, however, in most of the common solvents, plasticizers, and resins. The Aroclor oils and resins are readily soluble in most of the common organic solvents and drying oils. Hard crystalline Aroclor is in general less soluble than the liquid or softer Aroclor resins. Aroclor is heavier than water, a valuable property for many applications. MOHS 075846 6 Electrical Applications of Aroclor Aroclor is one of the purest commercial chemical compounds, virtually free of even traces of con ducting impurities. For this reason, dielectric properties of Aroclor closely approximate the theoretical maximum for these particular organic compounds. With its stability, heat-resistance and fire resistance -- Aroclor can be used for a variety of heavy-duty dielectric applications. DIELECTRICS FOR ASKAREL TYPE CAPACITORS AND TRANSFORMERS Aroclor is used per se in capacitors and is formu lated for the liquid coolant-insulation fluids in transformers. Such dielectrics must be highly pure with dependably minimal traces of electrolytes. They must be chemically stable and non-corrosive to a wide variety of structural materials. Most im portant, the dielectric fluid must be fire-resistant. Aroclor is the only liquid in low cost commercial supply that meets these exacting requirements. Aroclor liquids 1242, 1248, 1254, and 1260 are used directly, or are carefully formulated with chlorinated benzene and other additives to make askarel fluid for particular needs. Typical formu lated askarel fluids are shown on the following pages. Aroclor liquids 1242 and 1254, themselves or in special formulations, are used as the dielectric in fixed paper capacitors, for the power factor correc tion in utility transmission lines; for home ap pliances such as air conditioners, furnaces, washers and driers; for electric motors; and for ballast in fluorescent fixtures. There are also a number of applications in DC systems, in con densers, and the new energy storage capacitors. The Aroclor fluids can be used in a wide variety of applications requiring a specialized dielectric. Monsanto works closely with electrical equipment makers to develop the proper dielectric with the exact physical properties required by the engineer ing of the equipment. IMPREGNATING COMPOUNDS Because of its nonflammability, high resistivity, dielectric strength and low power factor, liquid and resinous Aroclor is extremely useful as an impregnating compound. An important applica tion of Aroclor in the electrical field is the use of Aroclor 1260, 4465, and 5460 in wire or cable coatings and as impregnants for cotton and asbes tos braided insulation. Because they possess high purity and excellent electrical resistance, Aroclor 1254, 5460 and 1268 make superior dielectric sealants to close the pores of carbon resistors, and to seal electrical bushings and terminals. To attain the lowest possible loss factor and gain resistivity, Aroclor is often treated with about 0.20% by weight of Attaupulgus clay or Fullers earth. To activate the earth it should be heated to 450a-500aF. DMmM* CMKtMt it 1,DN Cyotn (1) AtmIw ZS'C 1MC Velum* ResiitfvHy (2) Ohm-im <t 100C, 600 Vifti D.C.

Aroclor liquid is used as the actuating medium in bellows controls, thermo stats, industrial temperature control regulators and other kinds of automation equipment. The average coefficient of expansion of Aroclor 1248 per degree F within the various temperature ranges indicated in the table below was determined by using the simple formula Vt - Vt' (1 + a (t -- t,).] The coefficient a, has been calculated at 100F increments as follows: Ttmp.

In the trough of an nealing furnaces, for example, Aroclor makes de pendable fire-safe roof seals. VACUUM DIFFUSION PUMP OIL Fluid Aroclor 1248 and 1254 are highly stable to air; they make good oils for vacuum pumps at a much lower cost than high priced silicone type oils. Aroclor operates efficiently in vacuum diffusion pumps used to pull high vacuum for metalizing plastics, dehydrating foods, medicinals, and for drying capacitor cones. LIQUID SEALANT FOR FURNACE ROOFS Because of their low vapor pressures and fireresistance, Aroclor 1248 and 1264 make excellent liquid sealants. These non-evaporating fluids have good flow at slightly elevated temperatures and are chemically stable at elevated temperatures. Consequently, Aroclor liquid makes excellent fluid MCNS 075851 Aroclor in Special Product Formulations With their wide range of physical properties, their inertness, lubricity, and vapor-suppressing char acteristics -- Aroclor chlorinated compounds can be valuable ingredients in an extraordinary variety of formulated products. They are compatible with a variety of solvents, oils and resins. Virtually non-vointile and permanently thermoplastic, they will not react with other chemicals in the formula tion. In addition, their low cost makes their use for special purposes eminently practical and eco nomical. SEALERS FOR GASKETS Aroclor -- particularly when hot -- swells rubbers like Hycar*, Koroseal*, PerBuna N, and Neo prene. Wherever seals and gaskets of natural or synthetic rubber tend to shrink under heat and use, Aroclor 1232, 1242, or 1254 can be used as a swelling agent to tighten the shrunken seal. An example is in automotive transmission oil: a small amount of Aroclor in the oil swells the seal in place, saving the cost of tearing down the equip ment to replace the seal or gasket. Aroclor can be used in gasket sealing compounds to swell the rubber after the gasket or seal is in place. DEDUSTING AGENT Aroclor 12G4 w a low cost dedusting agent which can hold down the dusting of a variety of chemical products! Because Aroclor 1254 resists both com bustion and oxidation, it can be used to control dusting of highly reactive compounds. As a typical example,(1) a few tenths of one percent will con trol the dusting of calcium hypochlorite. ttym KmmIw* rsaMmdfcrtMM'hiof I. f. awtrM Ot. (I) OmM * * I- MM *. Ufl.lll. DM iMMwr i*. IN*.

United States Department of Agriculture scient ists reported that the inclusion of from 5 to 25 parts per hundred by weight of Aroclor increased the effective kill-life of a lindane spray up to ten times. A painted or metallic surface sprayed with certain chlorinated insecticides fortified with Aroclor will remain toxic to flies, ants, roaches and silverfish up to 2 to 3 months. The Aroclor resins suppress the rapid evaporation of the volatile insecticides without adding odor or other objec tionable residue. Formulation into insecticides is quite simple: the Aroclor is dissolved in a suitable solvent compatible with the insecticide formula tion, and mixed in. The most pronounced effect for increasing the kill-life of the insecticide is ob tained with lindane, chlordane and BHC. Aroclor is recommended for chlorinated insecticide formu lations to be used for non-crop spraying. Their low cost makes this use a most practical way to lower the ultimate cost of insect control. PRECISION CASTING WAXES Aroclor is compatible with various natural waxes, such as camauba and others, including those used to formulate casting wax. Aroclor helps impart to the finished casting wax a number of desirable properties: hardness without brittleness; resist ance to shrinking; sharp definition; sharp melting point; and fire-resistance. Waxes formulated with Aroclor are non-tacky and highly stable. Waxes containing Aroclor are widely used in making dental castings, in the precision casting of aircraft parts, and for casting costume jewelry. Aroclor 1264, 4465 and 5460 are most frequently used .. . proportions dependent upon the properties re- \ ti t i MOM* 075852 T2 quired in the finished wax. Much of the highest quality precision casting wax used in the lost wax process is formulated with Aroclor. AROCLOR IN ABRASIVES Aroclor 1264,1268 and 6460 are used in the manu facture of specialized abrasives. Because of their excellent bonding characteristics, high thermal stability and resistance to oxidation and corrosion -- Aroclor is used as the carrier for abrasive ma terials. A major use is as part of the bonding agent in specialized grinding wheels. AROCLOR IN SPECIALIZED LUBRICANTS For specialized lubricants requiring good extreme pressure (EP) characteristics, the Aroclor liquids make excellent additives. They impart high tem perature stability, excellent lubricating qualities, and weather and corrosion resistance. As an ex ample, Aroclor is used to formulate grease and pipe thread compounds for use in oxygen systems. Greases formulated with Aroclor have a high chemical resistance and are suitable for use in contact with corrosive chemicals. Gear oil lubri cants containing Aroclor have good resistance to sheer degradation and high temperature stability. Added in small amounts to railroad car journal box oils, Aroclor imparts better extreme pressure lubricity and reduces the incidence of hot boxes. The heat-resisting, nonflammable characteristics of the Aroclor chlorinated compounds make them attractive in themselves as lubricants under condi tions of high temperature. As an example: in gov ernor systems of central power stations, A odor 1248 is well suited to this lubricating application. Straight Aroclor 1254 gives excellent results on a roller bearing test operating at 256-260F with much less carbonization or decomposition than the usual spindle oil under the same conditions. As an extreme pressure (EP) lubricant base added to a petroleum hydrocarbon oil in amounts up to approximately 15% by weight, Aroclor 1248 and 1254 materially increase the load-carrying proper ties without reducing the viscosity of the resulting composition. These two compounds represent one of the more satisfactory carriers for the element chlorine as an extreme pressure base, possessing the following advantages: 1. STABILITY. Even at higher temperatures, there will be neither separation of components nor appreciable change in physical or chemical properties during long periods of operation. 2. NON-VOLATILE. Many other types of chlo rine bearing compounds are so volatile as to render them unfit for long periods of service. Aroclor is non-volatile at normal temperatures. 3. NON-OXIDIZING. Aroclor does not oxidize nor thicken up to an objectionable degree. 4. NON-CORROSIVE. Aroclor does not attack metal surfaces. 5. NON-ABRASIVE. Aroclor exerts no abrasion on the machined surfaces. 6. NON-HYDROLYSIS. Aroclor docs not hy drolyze in the presence of water, thus avoiding the generation of hydrochloric acid. 7. COMPATIBILITY. Aroclor is completely miscible with mineral oils. 8. COLOR. Aroclor does not darken or change the color of lubricating oil.

The Aroclor functions as an excellent extremepressure lubricant and is far superior to aliphatic chlorinated hydrocarbons because of its higher order of thermal stability. The heat resistance is most important in cutting oils for machining high grade steel. With Aroclor cutting oils there is a lower degree of hydrolysis which minimizes the staining of the metal. *0*$ 075854 14 Appendix Methods for Emulsifying and Making Stock Solutions of Aroclor There arc several simple methods for making Aroclor emulsions; the one used may be selected to suit the kind of Aroclor and type of formulation in which it will be used. Emulsifying Viscous Aroclor (Portion 1) 16 lbs. of Aroclor 1 lb. of stearic acid (Portion 2) 8 lbs. of water 4 oz. Triethanolamine Heat the Aroclor to a workable viscosity (180#F plus) and stir in the stearic acid thoroughly. Hent the water to almost boiling (207*F) and stir in the triethanolamine thoroughly. Pour the Aroclor stearic acid portion into the water portion, agitat ing vigorously. Then process the combined por tions with a highspeed emulsifying stirrer ... or process through a colloid mill. Emulsifiablo Concsntratsd Stock Solutions of Aroclor 79 parts of Aroclor 16.70 parts of toluene 3.55 parts of isopropyl alcohol 1.00 parts of Stcrox*' CD non-ionic emulsifier 0.75 parts of Santomerse1 anionic wetting agent The above formulation is readily emulsifiable with water. If a more resinous Aroclor is used, increase the amount of toluene (or xylene) as needed to dissolve the Aroclor resin.

SAYSOLT UN VISCOSITY RANGES OF SOME OF THE AROCLOR CHLORINATED COMPOUNDS HONS 075860 DENSITIES OF AROCLOR CHLORINATED COMPOUNDS AT VARIOUS TEMPERATURES ABSOLUTE DENSITY (G M S./CC) HONS 075861 21 r Dermatology and Toxicology At ordinary temperatures the Arocior poly chlorinated polyphenyls have not presented in dustrial toxicological problems. The hazard of potential toxic exposure varies with their vola tility: the lower-chlorinated ones, being more volatile, present more of a potential problem from the standpoint of both inhalation and skin con tact. When Arocior is used at elevated tempera tures, engineering controls must be applied, either by the use of closed systems or by effective localexhaust ventilation together with general work room exhaust. Inhalation tests on animals indicate that the maxi mum safe concentration of vapor is in the range of 0.6 to 1.0 milligram of the lower-chlorinated Aro cior compounds per cubic meter of air. The thresh old limits (maximum allowable concentration for an 8-hour working day) set by the American Con ference of Government Hygienists are 1.0 milli gram of the lower-chlorinated Arocior compounds per cubic meter of air and 0.5 milligram of the more-highly-chlorinated compounds, such as Aro cior 1254, per cubic meter of air. Schwartz patch tests on 200 volunteers showed that neither Arocior 1254 alone when applied to gauze nor a polyvinyl chloride film containing 11.5-weight-per cent Arocior 1254 was a primary irritant or a sensitizer. Canvas coated with an oilmodified alkyd resin (17-weight-per cent of the paint-film solids and 7-weight-per cent of the painted fabric was Arocior 5460) did not produce primary skin irritancy or sensitization according to the same Schwartz technique. Continuous or re peated skin contact with Arocior must be avoided because of the possible occurence of a condition called chlorance. Although reports of th:s condi tion caused by Arocior are rare, it can be produced by excessive skin contact. HONS 075862 22 Safe Handling Vapors of the Aroclor liquids at room temperature should not be breathed in a confined space. Vapors evolved at elevated temperatures should not be allowed to be dispersed into the general workroom. Instead, engineering control must be applied to reduce vapor concentrations below the allowable concentrations mentioned above. Continuous or repeated skin contact with Aroclor must be avoided by the use of gloves and pro* tective garments. If any Aroclor is spilled on the skin, the skin should be washed in the usual man ner with a soap solution. A bum caused by contact with a hot Aroclor should be treated like any ordinary bum. Aroclor adhering to the burned area need not be removed immediately, unless treatment of the burn de mands it, in which case either soap and water or repeated washings with a vegetable oil are recom mended.
