WEBAug 10, 2015 — Perfluorooctanoic acid (PFOA), or pentadecafluorooctanoic acid, is a colorless liquid with a boiling range of 189–192 ºC. Its chief use is as a surfactant in the emulsion polymerization of fluoropolymers such as poly(tetrafluoroethylene) (Teflon). It is invaluable in the production of microchips.
