Ordinary PTFE has better mechanical properties, electrical properties, chemical resistance, creep resistance, processability, etc., and its advantages are more obvious in engineering fields that require higher safety and reliability.
Modified tetrafluoroethylene.
(1) Adding tin bronze powder, glass fiber, silicon dioxide, molybdenum disulfide, graphite to pure PTFE can enhance its mechanical strength, lubricating performance, thermal conductivity, wear resistance, etc., and can be used to manufacture various types of machinery. Lubricated and wear-resistant bearings, piston rings, etc.
(2) High copper powder filled with PTFE can not only ensure the mechanical properties of the original metal parts, but also enhance (wear-resistant, plastic).
(3) Adding 20% para-polyphenyl to PTFE powder can increase the temperature resistance range of the finished product, and make the product work at a temperature of -150℃～+280℃.
(4) Filled with PTFE can replace bearing bushes on rolling mills, which can reduce noise and prolong service life.
