PTFE

The Chinese name of PTFE is Poly tetra fluoro ethylene ptfe emulsion, which is a polymer chemical material containing polytetrafluoroethylene. It is widely used in packaging, electronics, electrical engineering, chemical energy, corrosion resistant materials, and high-performance special coating is a fluoro coating based on polytetrafluoroethylene. The English name is Teflon. Because of its pronunciation, it is often called Teflon, Teflon Teflon, Teflon, etc.

2. Common applications of PTFE

Polytetrafluoroethylene is known as the "king of plastics". Roy Plunkett, the father of fluororesin, began to study the substitutes of Freon in DuPont in 1936. They collected some tetrafluoroethylene and stored it in steel cylinders for the next experiment the next day. But when the cylinder pressure relief valve was opened the next day, there was no gas overflow. They thought it was gas leakage, However, when weighing the cylinder, it was found that the cylinder did not lose weight. They sawed open the cylinder and found a large amount of white powder, which was polytetrafluoroethylene.

3. Development history of PTFE

The Chinese trade names are "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", etc. It is a polymer compound polymerized from tetrafluoroethylene. Its structural formula is - [- CF2-CF2 -] n -. It has excellent chemical stability and corrosion resistance. It is one of the best corrosion resistant materials in the world today. Except for molten alkali metal, chlorine trifluoride, chlorine pentafluoride and liquid fluoride, it can resist all other chemicals and does not change when boiled in aqua regia, It is widely used in various occasions where acid and alkali resistance and organic solvents are required. It has sealing property, high lubrication and non adhesion, electrical insulation, good anti-aging ability, and excellent temperature resistance (it can work for a long time at the temperature of+250 ℃ to - 180 ℃). Teflon itself is not toxic to humans.
