Extrusion PTFE rod bar is manufactured by continuously extruding PTFE paste resin under controlled temperature and pressure conditions. This process produces rods with uniform structure, fine surface finish, and greater length continuity compared with molded PTFE rods. They maintain the same excellent chemical resistance, dielectric strength, and thermal stability, while offering improved flexibility for applications requiring long sections or lightweight components.
Typical uses include insulation rods, sealing pins, pump shafts, and mechanical slide parts in electrical, chemical, and precision machinery industries. Various diameters and lengths of extrusion ptfe rod bar can be customized according to engineering needs.
