Aroclor 1221 Use and Manufacturing

In polyvinyl acetate to improve fiber-tear properties; plasticizer for polystyrene; in epoxy resins and polyvinyl acetate to improve adhesion and resistance to chemical attack; as an insulator fluid for electric condensers and as an additive in very high pressure lubricants. In fluorescent and high-intensity discharge ballasts manufactured prior to 1979 (U.S. EPA, 1998).
At a concentration of 5 to 25 wt %, increased the effective kill-life of the lindane spray up to 10 times. May have
