Chemours Teflon™ FEP 9898 Melt-processible fluoroplastic resin
Categories:	Polymer; Thermoplastic; Fluoropolymer; Fluorinated Ethylene Propylene (FEP); Fluorinated Ethylene Propylene (FEP), Molded/Extruded
Material Notes:	Teflon™ FEP 9898 is a melt-processible fluoroplastic resin available in pellet form. It is a copolymer of tetrafluoroethylene and hexafluoropropylene, without additives, that meets the requirements of ASTM D 2116 Type II. With a relatively high melt flow rate and improved high frequency electrical properties, Teflon™ FEP 9898 has been designed for high-speed extrusion of thin coatings on small-gauge wires. Applications for Teflon™ FEP 9898 include small diameter, thin wall wire and cable insulation; industrial film; and intricate or thin wall parts made by injection molding.
