Skeletal structure of PFOS, an effective, persistent and bioaccumulative fluorosurfactant A physical sample of PFOA, appearing as a white solid as seen here in a relatively pure form. It is commonly referred to as the main harmful PFAS chemical and PFOA is responsible for many of the negative health effects commonly associated with PFAS.
Perfluoroalkoxy alkanes (PFA) are fluoropolymers. They are copolymers of tetrafluoroethylene (C 2 F 4) and perfluoroethers (C 2 F 3 OR f, where R f is a perfluorinated group such as trifluoromethyl (CF 3)). The properties of these polymers are similar to those of polytetrafluoroethylene (PTFE). Compared to PTFE, PFA has better anti-stick ...
