Chemours Teflon™ CJ 99 FEP Resin
Categories:	Polymer; Thermoplastic; Fluoropolymer; Fluorinated Ethylene Propylene (FEP); Fluorinated Ethylene Propylene (FEP), Molded/Extruded
Material Notes:	Teflon™ FEP CJ 99 is a melt-processible copolymer of tetrafluoroethylene and hexafluoropropylene, without additives, that meets the requirements of ASTM D 2116 Type I. This resin offers both attractive processing speeds and high stress-crack resistance in addition to the excellent characteristics typical of Teflon™ fluoroplastic resins, such as non-aging characteristics, chemical inertness, exceptional electrical properties, low flammability, heat resistance, toughness and flexibility, low coefficient of friction, non-stick characteristics, negligible moisture absorption, and excellent weather resistance. The increased transparency of Teflon™ FEP CJ 99 will also allow better color ability. Information provided by Chemours.
