PTFEfilled
PTFE-filled refers to a family of polymer composites in which polytetrafluoroethylene (PTFE) is blended with solid fillers to tailor performance for engineering applications. The goal is to modify PTFE's properties—such as wear resistance, stiffness, creep resistance, thermal conductivity, and dimensional stability—while maintaining its chemical resistance.
Fillers commonly used include graphite or carbon, bronze, stainless steel, glass fibers, silica, alumina, and ceramic
PTFE-filled composites are typically produced by blending PTFE powder with fillers, forming by extrusion or molding,
Applications include bearings, bushings, seals, valves, and sliding components in chemical processing, food equipment, and general
