PTFE rods are divided into molded rods and extruded rods, the difference is mainly manifested in the difference in the production process. Teflon molded rod is made of polytetrafluoroethylene resin by molding method at room temperature and then sintered. The PTFE extruded rod is made of polytetrafluoroethylene resin with a certain amount of extrusion aid, formed by paste extrusion method, and then sintered at high temperature.

PTFE rod is an unfilled PTFE resin suitable for processing various gaskets, seals and lubricating materials that work in corrosive media, as well as electrical insulating parts used under various frequencies. Rod formed by molding, paste extrusion or plunger extrusion processes.
PTFE rods are used to manufacture gasket sealing and lubricating materials that work in various corrosive media and electrical insulating parts used under various frequencies.
So what are the advantages of PTFE rods?
1. No adhesion: low surface tension, no adhesion to any substance;2. Very small friction coefficient and good lubrication characteristics;3. Large space for weather resistance and temperature resistance: long-term performance in the atmosphere remains unchanged, and can work for a long time at a temperature of +260°C to -180°C;4. Non-toxic: It is physiologically inert, and it is a non-toxic and harmless product within 280℃;5. Corrosion resistance: resistance to strong acids, alkalis, aqua regia and various organic solvents (except molten sodium and liquid fluorine) and other chemicals;6. High insulation: low dielectric constant and dielectric loss, high withstand voltage, and excellent insulation;7. Non-combustibility: it will be extinguished after leaving the open flame, good flame retardant material.
