PFA is a resin very similar to FEP in use, but PFA can be used at even higher continuous use temperatures (500°F), can be applied thicker, and has greater toughness than PTFE & FEP. PFA is useful for the paper industry where it helps to improve the efficiency of paper mills, pulp mills and other paper converting industries where it prevents fibers from sticking to process equipment which can cause quality problems and result in expensive downtime and cleaning.
