GenX

GenX is the trade name for a processing aid technology used to manufacture high-performance fluoropolymers without perfluorooctanoic acid (PFOA). “GenX chemicals” generally refers to hexafluoropropylene oxide dimer acid (HFPO-DA) and its ammonium salt, the two main chemicals associated with this technology. Both belong to the PFAS family. Their resistance to environmental degradation makes them a concern when released into water, and replacing PFOA with GenX chemicals does not eliminate PFAS pollution risks.
