Chemie und Industrie
Anwendungen
VerwendenDielectric liquids; in fixed paper capacitors; heat-transfer liquid widely used in transformers and utility transmission lines; swelling agents for transmission seals; ingredient in lubricants, oils, and greases; plasticizers for cellulose products, vinyl, and chlorinated rubbers; in polyvinyl acetate to improve fiber-tear properties. In fluorescent and high-intensity discharge ballasts manufactured prior to 1979 (U.S. EPA, 1998) and in electric motors (Monsanto, 1960). Prior to being banned in 1976, PCB-1254 was used in home appliances including air conditioners, furnaces, washers, and driers. May have been added to automotive transmission oils to swell shrunken transmission seals in place (Monsanto, 1960). At a concentration of 5 to 25 wt %, increased the effective kill-life of the lindane spray up to 10 times. May have been used in chlordane and BHC insecticide formulations. In polyvinyl acetate emsulsions to impart strong bonding power in adhesives. In various nitrocellulose lacquers to impart weather resistance, luster, adhesion, and decreased burning rate. These lacquers may also contain tricresyl phosphate (Monsanto, 1960).
