PFA
Perfluoroalkoxy (PFA) is a high performance, melt-processible fluoropolymer. It performs exceedingly well in extreme thermal and chemical environments. It exhibits similar characteristics to PTFE. Typical applications include pump housings and pipe linings, tanks, semiconductor wafer carriers, food processing and packing equipment
