POLYTETRAFLUOROETHYLENE (PTFE)

PTFE is a chemically modified polytetrafluoroethylene polymer. When properly processed, Teflon® exhibits the superior properties typical of the fluoropolymer resins: nonaging characteristics, chemical inertness, heat resistance, toughness and flexibility, low coefficient of friction, nonstick characteristics, negligible moisture absorption, and weather resistance, improved resistance to deformation under load and a higher dielectric breakdown voltage. This resin provides a high degree of weldability for applications where the use of elevated pressure and temperature are limited.
PTFE is a fine-cut resin designed for general compression molding of blocks and sheets and for use as a base resin for compounds. It can be used for such applications as: seal rings, valve seats, bearing pads, linings, encapsulations, and as a base resin for filled compounds.
