CLOPHEN Chemical compatibility with O-rings, rubbers, & plastics

Clophen is a trade name for polychlorinated biphenyls, commonly known as PCBs, which were historically used as dielectric coolants and insulating fluids in electrical equipment. These chlorinated aromatic compounds are highly toxic and environmentally persistent, with strict regulations governing their use and disposal. In systems where Clophen or PCB fluids are present, O-rings, rubber seals, gaskets, and plastic components must be carefully evaluated for chemical compatibility. Proper handling, storage, and compliant disposal practices are essential for safety and environmental protection.
