Chemours Teflon™ 9302 FEP Resin
Categories:	Polymer; Thermoplastic; Fluoropolymer; Fluorinated Ethylene Propylene (FEP); Fluorinated Ethylene Propylene (FEP), Molded/Extruded
Material Notes:	Teflon™ FEP 9302 is a melt-processible copolymer of tetrafluoroethylene and hexafluoropropylene, without additives, that meets the requirements of ASTM D 2116 Type IV. It offers the excellent combination of properties characteristic of Teflon™ fluoroplastic resins: non-aging characteristics, chemical inertness, exceptional dielectric properties, low flammability, heat resistance, toughness and flexibility, low coefficient of friction, non-stick characteristics, negligible moisture absorption, and excellent weather resistance. Teflon™ FEP 9302 is used in the chemical industry for applications, such as chemical linings, bellows, valve components, pipes, and tubing. In demanding wire and cable applications, requiring a very high degree of stress crack resistance, it can be used as a material for jacketing. Applications: Tubes, piping, linings, bellows, valves, and other components for the chemical industry. Jackets for wire and cable applications demanding a high degree of stress crack resistance.
