Teflon™ FEP 9898 by Chemours is tetrafluoroethylene and hexafluoropropylene (FEP) copolymer without additives. It is a melt-processable fluoroplastic resin that provides good dielectric & non-aging properties, good toughness, low coefficient of friction and moisture absorption. Exhibits low flammability, good flexibility, low smoke, chemical inertness & high weather-, water and ignition resistance. Teflon™ FEP 9898 is suitable for processing by melt extrusion & injection-, compression- and transfer molding. Used in small diameter, thin wall wire & cable insulation and industrial film. Meets the U.S. Environmental Protection Agency (EPA) 2010/15 PFOA regulations and ASTM D 2116 type II.
