Polytetrafluoroethylene (PTFE) is one of the best corrosion-resistant materials in the world, so it is known as the "King of Plastics". It can be used in any kind of chemical medium for a long time, and its generation has solved many problems in chemical industry, petroleum, pharmaceutical and other fields in China. Polytetrafluoroethylene sealing parts, gaskets, gaskets. Polytetrafluoroethylene sealing parts, gaskets, gaskets are made of suspension polymer resin moulding. Compared with other plastics, PTFE has excellent chemical corrosion resistance and temperature resistance. It has been widely used as sealing material and filling material.
Polytetrafluoroethylene is a polymer of tetrafluoroethylene. The English abbreviation is PTFE. The trade name is teflon. It is praised as "the king of plastic". Polytetrafluoroethylene (PTFE) is widely used in a variety of applications requiring acid-base resistance and organic solvents. It is not toxic to human beings, but ammonium perfluorooctanate (PFOA), one of the raw materials used in the production process, is considered to have carcinogenic effects.
(Teflon or PTFE), commonly known as "Plastic King", Chinese trade names "Teflon", "Teflon", "Teflon", "Teflon" and so on. It is a macromolecule compound synthesized from tetrafluoroethylene. It has excellent chemical stability, corrosion resistance, airtightness, high lubrication and non-stickiness, electrical insulation and good aging resistance. It can work for a long time at temperatures ranging from +250 to -180 degrees C. Besides molten metal sodium and liquid fluorine, it can withstand all other chemicals and boil in aqua regia unchanged.
As engineering plastics, it can be made into PTFE tubes, rods, strips, plates, films, etc. Generally used in high performance requirements of corrosion-resistant pipelines, containers, pumps, valves and radar, high-frequency communication equipment, radio equipment and so on. In 2002, Tianjin Donghao Polytetrafluoroethylene Products Co., Ltd., a subsidiary of Tianjin Donghao Hose Technology Co., Ltd., took the lead in introducing Japan's advanced technology and equipment and successfully developed and produced domestic advanced products such as hoses, PTFE spiral hoses, PTFE steam hoses and PTFE high-pressure hoses.
Dispersion solution can be used as insulation impregnating solution of various materials and anti-corrosion coating of metal, glass and pottery surface. All kinds of PTFE rings, PTFE gaskets, PTFE panels are widely used in various anti-corrosion pipeline flange sealing. In addition, it can also be used for drawing, fiber - fluorocarbon (foreign trade name is Teflon).
At present, all kinds of PTFE products have played an important role in the fields of chemical industry, machinery, electronics, electrical appliances, military industry, aerospace, environmental protection and bridges.
