PTFE is a kind of polymer material, full name is polytetrafluoroethylene, English name is polytetrafluoroethylene. The material is made by the polymerization of multiple tetrafluoroethylene molecules, which has good chemical stability, high temperature resistance and low friction coefficient, so it is widely used in various fields.

PTFE was first discovered and put into production by DuPont in 1938. Because of its unique properties, it is widely used in production, manufacturing, electronics, construction and other fields. Its most notable feature is that it does not deform at high temperature, can be used in the range of -260 ℃ to 260 ℃, and has good electrical insulation properties, corrosion resistance and oxidation resistance. At the same time, PTFE has a very low viscosity and friction coefficient, which can effectively reduce friction resistance and noise.

In the field of manufacturing, PTFE is widely used in various molds, molds, bearings and pipes. Because of its high corrosion resistance and chemical stability, it can be widely used in chemical, pharmaceutical and food industries. At the same time, PTFE can also be used as paints, coatings, paper products, fibers and plasticizing materials, and can be used as an important basic material for processing, modification and research.

In the electronics industry, PTFE is used in high-temperature wire and cable insulation, capacitors, electrodes and other fields. PTFE material not only has good insulation properties, but also can withstand high voltage and high temperature, so it is widely used in the manufacture and maintenance of electronic devices. In addition, PTFE is also widely used in the manufacture of high-temperature moving mechanical parts, bearings, rings and other fields.

PTFE is a polymer material with good chemical stability, high temperature resistance and low friction coefficient, which is widely used in various fields, such as manufacturing, chemical industry, electronics, construction and so on. With the continuous development of science and technology, PTFE materials will play a more important role in modern industry.
