What is PFA
Perfluoroalkoxy or PFA is a perfluoropolymer, which has essentially the same chemical resistance as PTFE has added molding properties and is ideal for lining complex shapes.
PFA is extensively used in Ultra-Pure applications. It has excellent creep resistance at high temperatures with good flame resistance and reasonably tough at low temperatures. PFA can be used in combination with PTFE lined pipe for handling most chemical fluids.
