Chemours Teflon™ 807N X Granular PTFE Resin
Categories:	Polymer; Thermoplastic; Fluoropolymer; Polytetrafluoroethylene (PTFE); Polytetrafluoroethylene (PTFE), Molded
Material Notes:	Teflon™ PTFE 807N X is a free-flowing PTFE granular resin designed for compression or automatic molding and ram extrusion (low back pressure). It offers an excellent combination of properties that are characteristic of Teflon™ fluoroplastic resins. Teflon™ PTFE 807N X is a multi-purpose PTFE resin that yields high productivity due to its high fill density. It is easy to process, handle, and machine. It also has excellent end-use properties. Applications: Can be fabricated into billets for skived tape, basic shapes, and moldings. It can be used for applications such as: Seals, Valve seats, Bearing pads, Linings, Gaskets, Electrical/electronic parts. Information provided by Chemours.
