PCB 1254 Use and Manufacturing

Secondary plasticizer for polyvinyl chloride; co-polymers of styrene-butadiene and chlorinated rubber to improve chemical resistance to attack. In fluorescent and high-intensity discharge ballasts manufactured prior to 1979 (U.S. EPA, 1998).
Sealing electrical bushings and terminals. Used instead of silicone oils in vacuum pumps. May have been added to automotive transmission oils to swell shrunken transmission seals in place. Ingredient in emulsifiable-type cuttings oils to increase
