Teflon PFA Copolymer Rod

Formula: PFA

Form: Rod

Material: Perfluoroalkoxy (Teflon-PFA)Perfluoroalkoxy (Teflon-PFA)

Commodity: Polymers

Teflon PFA Copolymer Rods are part of our wide range of polymer rods and come in 32 variations. They’re made from a copolymer of tetrafluoroethylene and perfluoroalkylvinylether, giving them excellent chemical resistance as well as high-temperature stability. Teflon PFA rods are used in the chemical processing, semiconductor and oil/gas industries, where corrosion resistance is paramount. They can be machined into bushings, spacers and other components for use in harsh environments. With a wide choice of sizes available our Teflon PFA Copolymer Rods provide versatile, high-performance solutions for diverse applications.
