PTFE (polytetrafluoroethylene), also known as Teflon, has excellent chemical stability and corrosion resistance. It is one of the best corrosion resistance materials in the world. It is widely used in various anti-acid and alkali solvents. The occasion. Sealed, highly lubricated and non-tacky, electrically insulating and good anti-aging ability, excellent temperature resistance (can work for a long time at temperatures from 250 ° C to minus 180 ° C). In addition to molten alkali metal, chlorine trifluoride, chlorine pentafluoride and liquid fluorine, PTFE can withstand all other chemicals, does not change in boiling water in aqua regia, and PTFE itself is not toxic to humans. In daily life, we also see PTFE plastic products. It is on the most familiar nonstick pan.
Teflon is one of the most important ones of fluoroplastics, and it has the reputation of “Plastic King” in the industry. Frankly speaking, Teflon's strength is not high, compared to nylon, which is simply slag, but in addition, Teflon shows outstanding performance in heat and cold resistance, and in terms of corrosion resistance, it It is a well-deserved king. The general acid and alkali are pediatrics for it. Even Wang Shui has nothing to do with it. In addition, it both repels oil and repels water, so when you use non-stick pan, you can see that whether it is oil or water, it will exist in the form of liquid beads. People familiar with physics understand that this is the surface tension, and therefore Teflon is also widely used in industry, especially in the chemical industry. Pipeline and reaction equipment. Teflon-made plastic products are neither corrosive nor easy to clean. They are naturally popular.
Its production solves many problems in the chemical, petroleum, pharmaceutical and other fields. PTFE seals, gaskets, gaskets. PTFE seals, gaskets, and gaskets are molded by suspension polymerization of polytetrafluoroethylene resin. Teflon is chemically resistant compared to other plastics and has been widely used as a sealing material and a filling material.
The dispersion can be used as an insulating immersion liquid for various materials and an anticorrosive coating for metal, glass, ceramic surfaces, and the like. Various PTFE rings, polytetrafluoroethylene gaskets, and PTFE packings are widely used in various types of anti-corrosion pipe flange seals. In addition, it can also be used for spinning, PTFE fiber - fluorocarbon (foreign trade name is Teflon). Nowadays, all kinds of plastic king products have played a pivotal role in the national economy such as chemical industry, machinery, electronics, electrical appliances, aerospace, environmental protection and bridges.
Polytetrafluoroethylene (PTFE) conditions for use in chemical, petrochemical, refining, chlor-alkali, acid, phosphate, pharmaceutical, pesticide, chemical fiber, dyeing, coking, gas, organic synthesis, non-ferrous smelting, steel, atomic energy and polymer filtration materials Production of high-purity products (such as ion-exchange membrane electrolysis), transportation and operation of viscous materials, and food processing and production departments with strict requirements for hygiene.
