PTFE Powder (Polytetrafluoroethylene)
PTFE (polytetrafluoroethylene) powder is supplied in free-flowing micronized and molding grades for coating additives, compression molding, and sintered component production. It offers an extremely low coefficient of friction, broad chemical inertness, and continuous service up to roughly 260°C. Typical particle size ranges from about 1 to 35 µm for micronized grades; grades and particle size are confirmed at time of quotation.
