PFA: High-Purity Fluoropolymer for Chemical and Pharmaceutical Processes

PFA (perfluoroalkoxy) is a top-of-the-range fluoropolymer, renowned for its exceptional thermal, chemical and mechanical performance. More flexible and more processable than PTFE, it nonetheless retains equivalent resistance to extreme chemicals.

Particularly used in the chemical, pharmaceutical, semiconductor and electronics industries, PFA guarantees purity, dimensional stability and durability under critical temperature and pressure conditions.
