Tetrafluoroethylene

A substance that is a possible carcinogen (cancer-causing agent) used in the production of polymers such as polytetrafluoroethylene. The US government in 2000 classified tetrafluoroethylene as "reasonably anticipated to be a human carcinogen." In laboratory animal studies of tetrafluoroethylene, cancer was observed in multiple organs of multiple species following long-term inhalation exposures.
