The unique Aroclor plasticizers are among the most versatile chemi cally produced materials available. One outstanding characteristic -- mertness -- makes Aroclor useful in many ways for many different 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
26 -- blend of chlorinated biphenyls and chlorinated triphenyls (7625)
44 -- blend of chlorinated biphenyls and chlorinated triphenyls (60:40)
64 -- 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.
'
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.

It is concluded that the vaporization rates of Aroclor plasticizers -- especially the most widely used 1254 and 1260 -- compare most favorably with the similar constants, of other plasticizers selected specifically for these tests because of their low vaporization rates.

The viscoiitiee of the Aroclor plasticizers vary according to whether the base material is a biphenyl or a polyphenyl and on the degree of chlorination. In general the low-chlorinated biphenyls have the lowest viscosities (Figure 8).

At ordinary temperatures the Aroclor chlorinated polyphenyls have not presented industrial toxicological problems. The hazard of potential toxic exposure varies with their volatility: the lower-chlorinated, morevolatile ones present more of a potential problem from the standpoint of both inhalation and skin contact. When Aroclor plasticizers are 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.
Vapor of the liquid Aroclor plasticizers at room temperature should not he breathed in a confined space, and no vapor of any Aroclor evolved at elevated temperatures should be allowed to be dispersed into the general workroom.
Inhalation teats on animals indicate that the maximum safe concen tration of vapor is in the range of from 0.5 to 1.0 milligram of the lower-chlorinated Aroclor plasticizers per cubic meter of air. The threshold limit values (maximum allowable concentration for an 8bour working day) set by the American Conference erf Government Hygienists are 1.0 milligram of the lower-chlorinated Aroclor com pounds per cubic meter of air and 0.5 milligram of the more-highlyehlorinateri compounds, such as Aroclor 1254, per cubic meter of air.
S/tit ftitttf
Schwartz patch tests on 200 volunteers showed that Aroclor 1254 was neither a primary skin irritant or a sensitizer.
Prolonged or repeated skin contact with the Aroclor plasticizers 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 Aroclor an rare, it can be produced by excessive akin contact. If any Aroclor is spilled on the skin the aldn should be washed in the usual manner with a soap solution.
A bum caused by contact with a hot Aroclor should be treated like any
ordinary bum. Aroclor plasticizer adhering to the burned area need
not be removed immediately, unless treatment of the burn demands
H, in which case either soap and water or repeated washings with a
vegetable oil an recommended.

Infinmetil Hutrtt Arodor 1232, Aroclor 1242, Arodor 1243, Aroclor 1254, Aroclor 1260, Arodor 1262, Aroclor 1268, Arodor 4465, and Montar 1 all contain polychlorinated biphenyls (PCB) of various types and in varying amounts. 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 pods, 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.
