Chemours Teflon™ PFA 345 Medium melt flow rate fluoropolymer resin
Categories:	Polymer; Thermoplastic; Fluoropolymer; Perfluoroalkoxy (PFA)
Material Notes:	Teflon™ PFA 345 is a medium melt flow rate fluoropolymer resin available in pellet form. Compared with Teflon™ PFA 340, it offers increased flex life and greater resistance to environmental stress-cracking (Teflon™ PFA 345 offers a typical MIT folding endurance of 50,000* compared to 15,000 in Teflon™ PFA 340). Applications for Teflon™ PFA 345 include extruded tubing, wire and cable insulation, injection molded parts, and chemically resistant linings for bellows, valves, fittings, pipes, pumps, and other fluid-handling components.
