PFA

Flexible fluoropolymer that performs well in extreme temperatures and harsh chemical environments

PFA (perfluoroalkoxy) is a tough, flexible fluoropolymer that is used for flexible tubing and fluid processing equipment when chemical resistance, high purity, and low stiffness are required. PFA has outstanding electrical properties including high dielectric strength, a low dissipation factor, and a low dielectric constant. The material has outstanding resistance to outdoor weathering. 

FDA Compliant PFA– Daikin Neoflon® GP. 

General Purpose PFA– DuPont™ Teflon® 350. 

Tech Tip– PFA has similar mechanical properties to FEP, but it has a higher service temperature than FEP and superior electrical properties compared with FEP.
