PTFE (PTFE) has excellent chemical stability, and is capable of all strong acids, alkalis, powerful oxidizing agents, and a variety of organic solvents do not take effect. PTFE has a wide temperature range, can be used for a long time at atmospheric pressure -180℃~250℃, at 250 ℃ high temperature treatment 1000h, its mechanical properties change very small. PTFE has a very low friction factor, is a good antifriction, self-lubricating material, its static friction coefficient is less than the dynamic friction coefficient, so used to make the bearing has a small starting resistance, smooth operation of the advantages. Because of the non-polarity of PTFE, heat and no water absorption, it is also an excellent electrical insulating material.
Also has excellent aging resistance, non-viscous and non-flammable. PTFE made of rods, tubes, films, bearings, washers, valves and other special-shaped materials and parts, widely used in machinery, chemicals, aviation, electrical and electronic, defense industry, cutting-edge technology, health and electrical insulation and other fields.
