One outstanding characteristic -- inertness -- makes Aroclor useful in many ways for many different v applications. The major benefits offered by Aroclor include: Chemical Resistance Fire Retardance Compatibility with most resins Nonoxidation Adhesivity Low Cost Monsanto's Aroclor plasticizers comprise a series of chlorinated bi phenyls and chlorinated polyphenyls. They vary from mobile, oily liquids to white crystals and hard, transparent resins. Twelve of the Aroclor plasticizers, each of which represents a series, are discussed in this bulletin. An understanding of the system for designation of each Aroclor should prove useful in the evaluation of the property gradations among them. The last two digits indicate the approximate weight percentage of chlorine in the product, and the first two digits indicate the type of material, as follows: 12 -- chlorinated biphenyls 25 -- blend of chlorinated biphenyls and chlorinated triphenyls (75:25) 44 -- blend of chlorinated biphenyls and chlorinated triphenyls (60:40) 54 -- chlorinated triphenyls For nearly every Aroclor mentioned, a darker, less-pure grade exists, with about the same physical and chemical characteristics, but lower in price. Solubility_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ ' The Aroclor liquids and resins are readily soluble in most common organic solvents and drying oils. Although all Aroclor plasticizers are insoluble in water, the hard, crystalline materials are generally less soluble than the liquids and softer resins. Solubilities of some Aroclor . plasticizers are shown in Table 1. o^n60 3 LEXOLDMON004690 WATER PCB-00030008 TABLE 1 SOLUBILITIES OF AROCLOR* PLASTICIZERS IN VARIOUS SOLVENTS Amchr 1242 Sofmrt_______________ 2FC Hat Andor124t 2FC Hot Andar 1254 2FC Hut Andor12tt CM Ha Acid Acetic Add Oleic Add Benzoic Add S s __ s s __ S s ---- s s ---- 10jprc -- 10.03" -- -- -- -- -- Aldehyde 40% Formaldehyde Forfaral 11111111 VS vs vs vs vs vs ss ss Amine Aniline Pyridine S 132.5^ s 440c -- -s s-- 1143TC 425WC -- -- Chloro derivatives Amyl chlorides -- mixed S s s s s s Carbon Tetrachloride s s $ s s s ---- Chloroform s sss s sss Dichlorethylene ---------------- Ethylene Bichloride s s s s s s s s Monochlorobenzene s s s s s s ---- QrthudidHurobeniene -- -- -- -- -- -- -- -- TetracMorsthane $ s s $ s s ---- TricMorethane s $ s s s s ---- Trichlorethylene s s s s s s ---- OryingOH Tang Oil Linseed OH s $ s s s s ---- ssss$s 1 s Ester Amyl Acetate $ss$ss$s Batyl Acetate ssssssss "Cel/osofre"' Acetate s s s s s s ---- Cottonseed OH s s s s s $ ---- Dibotyl Phthalate s s ss s sss Arvdor4465 Andor 5460 CM Hat 25~C ss s s vs ---- -- -- 11 vs vs -- -- vs vs vs vs -- vs vs vs vs 156 vs vs -- vs vs -- vs vs -- vs vs -- vs v$ -- vs vs -- vs vs -- vs vs -- vs vs vs vs -- -- vs vs vs vs vs vs s vs s vs -- -- -- - 0531861 LEXOLDMON004691 WATER PCB-00030009 Diethyl Pfcthatate S s s s s s - - s vs -- Ethyl Acetate S s s s s s ss ss s vs -- Ethyl lactate S s s s s s 1 s vs vs -- Ethyteoe Glycol Diacetate $ s s s s s -- -- vs vs -- Methyl Acetate s s s s $ s ss ss s s -- Incresyi Phosphate s s s s s s -- -- ss s -- Ether: Ethyl Ether s s s s s s s s s ---- Ether Alcohol CtrbttoT 22431-c 307t vs vs 173** 259sr* 1 s ss - -- Ceflosofn s s s s s s 1 s s ---- Diethylene dycol -------- -------- $ -- '-Dihydroxy Ethyl Ether lO.^ igerc ss ss 830c 10WC -- -- ss -- -- -- Hydrocarbon Benzene Gasoline Kerosene Mineral Spirits Paraffin Pine Oil Toleene Terpentine Xylene vs vs vs vs vs vs s s vs vs 143 vs VS vs vs vs vs -- -- vs vs -- vs VS vs vs vs vs ss s vs vs -- vs VS vs vs vs vs s s vs vs -- 2.02MC $ 2.02TC s --s -- -- 5.0 s -- s S vs vs $ s s s s s -- vs VS vs vs vs vs s s vs vs 142 vs VS vs vs vs vs s s vs vs -- vs VS vs vs vs vs s s vs vs 178 Hydroxy derivatives Amyl Alcohol _s s _ s s ss s s s e-Betyl Alcohol Ethyl Alcohol (3-A) s 23.y s 80.0*rc -- -- --s s 1 -- 1027-C 28* 1 ss ss 1 ss s -- -- -- Glycerine Methyl Alcohol 1 42.529c 1 88.5"* 1 -- 1111 -- 152TC 77 Test -- 111 -- ss -- -- -- Phenol --90% 194TM s -- -- ss s ss s s s -- Ketone: Acetone s s -- -- $ s 1 1 s s 260 Miscellaneous Carbon Disaffide Nitrobenzene Water s s -- -- s s s $ vs vs -- s s ---- s $ -- -- vs -- -- 1 1 1 1 1 1 1 1 1 1-- I --Insoluble SS -- Slightly Soluble S-Soluble VS -- Very Soluble.

The hazard of potential toxic exposure varies with their volatility: the lower-chlorinated, more- volatile ones present more of a potential problem from the] standpoint of both inhalation and skin contact. When Arodwptt&tieizeW hre used at elevated temperatures, engineering controls must be applied, either by the use of closed systems or by effective local-exhaust ventilation together with general workroom exhaust.

Inhalation tests on animals indicate that the maximum safe concen tration of vapor is in the range of from 0.5 to 1.0 milligram eHhe lower-chlorinated Aroelor plasticisers- per cubic meter of air. The threshold limit values (maximum allowable concentration for an 8hour working day) set by the American Conference of. Government Hygienists are 1.0 milligram of the lower-chlorinated mnw com pounds per cubic meter of air and 0.5 milligram of tbs more-highlychlorinated compounds, such mr Ai'oelei118W, per cubic meter of air. Skit Cttltcl Prolonged or repeated skin contact with the Aroelor piaswcisew must be avoided by the use of gloves and protective garments, because of the possible occurrence of a condition called chloracne. Although re ports of this condition caused by jtMsci|r are rare, it can be produced by excessive skin contact. If aaywwlw is spilled on the skin the skin should be washed in the usual manner with a^oap solution. A burn caused by contact with a hot ^SSer should be treated like any ordinary burn.

PCB residues in small amounts have been found in the environment and some studies have indicated that they may be harmful to certain forms of animal life. Extreme care should therefore be taken by all users of PCB-containing products to prevent any entry into the environment through spills, leakage, use, disposal, vaporization or otherwise. Further, the products in which PCB materials are used, or which are formulated using PCB materials as a component, should be given careful study to eliminate the possibility that PCB might reach the environment as a result of use in a given application. Some specific applications where the use of PCB should definitely be avoided are in paints and sealants for swimming pools, paints and waterproofing agents in silos and other buildings where food products for humans or animals are stored, and as a component of any container or wrapping used in the packaging of food products. 0331872 1 13 LEXOLDMON004700 WATER PCB-00030018 Shipping Freight Classification Arodor 1221,1232,1242, Synthetic Resin, Liquid, NOIBN 1248,1254, 1260, 1262 Rail Classification Aroclor 1268, 4465, 5442, 5460 Synthetic Resin, Other Than Liquid, NOIBN Truck Classification Aroclor 1268 Aroclor 4465, 6442, 5460 Synthetic Resin, Powder, NOI Synthetic Resin, Lumps or Solid Mass, NOI Shipping Regulations None Standard Containers Aroclor 1221 Aroclor 1282 Aroclor 1242,1248,1254, 1260,1262 Aroclor 1268 Aroclor 4465 Aroclor 5442 Aroclor 5460 (flaked) Tank car, 520-lb. steel drum, 50-lb. can Tank car, 550-lb. steel drum, 60-lb. can Tank car, 600-lb. steel drum, 60-lb. can 200-lb. fiber drum, 25-lb. fiber drum 600-lb. steel drum, 50-lb. can 450-lb. steel drum, 50-lb. can 50-lb. bag 0531873 14 LEXOLDMON004701 WATER_PCB-00030019 V DISTRICT SALES OFFICES ALL DIVISIONS AKRON, OHIO 44313 260 Springside Drive Montrose Development Perk Tel.
