Teflon™ FEP 9835

Technical Datasheet | Supplied by Chemours

Teflon™ FEP 9835 by Chemours is a tetrafluoroethylene and hexafluoropropylene (FEP) copolymer. Used in thin wall wire & cable insulation, industrial film, high speed extrusion of thin coatings on small gauge wires for twisted-pair constructions and low voltage applications. Possesses good dielectric & non-stick properties, high melt flow rate, good toughness, low coefficient of friction and moisture absorption. Exhibits low flammability, good flexibility, low smoke, chemical inertness & high weather & ignition resistance. Teflon™ FEP 9835 is suitable for processing by melt extrusion & injection, compression and transfer molding. Meets the U.S. Environmental Protection Agency (EPA) 2010/15 PFOA regulations and ASTM D 2116 type II.
