Chemours Teflon™ PFA 340 General-purpose fluoroplastic resin
Categories:	Polymer; Thermoplastic; Fluoropolymer; Perfluoroalkoxy (PFA)
Material Notes:	Teflon™ PFA 340 is a general-purpose fluoroplastic resin available in pellet form. Compared with other grades of Teflon™ PFA, its most unique features are a relatively high melt flow rate (typical MFR of 14) and properties that make it suitable for a variety of processes and demanding end uses. Applications for Teflon™ PFA 340 include extruded tubing and other profiles for hose, wire and cable insulation, and sleeving; industrial film; and injection or compression molded articles requiring superior electrical, chemical, and thermal properties.
