PFA Properties

Physical, mechanical, thermal, electrical, and optical properties of PFA

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 and performs well in extreme temperatures. This flexible fluoropolymer is widely used for pump housings and pipe linings, fluid handling and chemical processing equipment, wet bench equipment, and food processing and packaging equipment.

PFA FDA Compliant grade is Daikin Neoflon® GP. Please ask your Curbell Plastics representative for more specific information.
