Propertles as Plasticizers
The Aroclor resins/plasticizers and their blends have an unusual combination of properties which make them extremely useful products. Their most important char acteristics are:
Low Cost
, ..
Highly Compatible
Chemically Stable
Fire Retardant
Excellent Adhesion
Another very useful aspect of this .product line is the fact that a continuous range of properties, can be achieved by using combinations of the Aroclors and their blends. Some of the physical properties which can be controlled . through product selection are shown on the following pages.
Our Aroclor product line is now made up of polychlorinated terphenyls, monochlorinated biphenyl, and blends of these products. None of these materials has been shown to create any environmental problems. On the other hand. Food and Drug Administration approval has not been obtained for any of these products. Accordingly, the Aroclor plasticizers should not be used in connection with food or food-related products, with food wrapping or food container materials. Further, Monsanto strongly recommends that these products not be used in any other application such as non-FDA re-
gulated food systems, in potable water systems, in any animal feeding systems, or in pharmaceuticals.

Key bo Nomenclature
5400 Series
These products are chlorinated terphenyls. The last two digits indicate the chlorine content of the material, e.g., Aroclor 5460 is a chlorinated terphenyl with 60 percent chlorine. Undistilled Aroclors are available and are designated by a 5000 series vs. the 5400 series. They are somewhat higher in color but otherwise have product characteristics similar to the distilled products.
6000 Series
These products are blends of Aroclor 5460 and Aroclor 1221-B, a biodegradable monochlorinated biphenyl. The last two digits are an indication of the proportion of Arocloi' 5460 in the blend, e.g., Aroclor 6062 has more Aroclor 5460 in it than does Aroclor 6050. ''
Miscellaneous Blends
'
Other product blends containing such other materials as Santicizer 140 for improved fire retardancy, or toluene/ xylene for lower viscosities will also be made available as the demand for these specialty products develops.

Toxicity and Safe Handling
Inhalation
.
At ordinary temperatures, the Aroclor chlorinated poly phenyls have not presented industrial toxicological pro blems. 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 Aroclor plasticizers are used at elevated tempera tures, 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 tempera
ture should not be breathed in a confined space, and no
vapor of any Aroclor eyolved at elevated temperatures
should be allowed to be dispersed into the general work
room. :
..
Skin Contact
Continuous 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 reports of this condition caused by Aroclor are rare, it can be produced by excessive skin contact. If any Aroclor is spilled on the skin, the skin should be washed in the usual manner with a soap solution.
A burn caused by contact with a hot Aroclor should be treated like any ordinary burn. Aroclor plasticizer adhering to the burned area need not be removed immed iately, unless treatment of the burn demands it, in which case either soap and water or repeated washings with a vegetable oil are recommended.
