What is the characteristics of a polytetrafluoroethylene (PTFE) seal? PTFE Seal ring PTFE Seal ring, also known as PTFE seal or Teflon seal ring, material referred to as PTFE or F4, is a polymer of tetrafluoroethylene. Dongpu seals tell you that the modified PTFE sealing material has the advantages of high temperature resistance, corrosion resistance, water resistance and aging resistance, and significantly improves and improves the service life of mechanical sealing equipment and pressure bearing capacity. The system has been widely used.
First, the characteristics of PTFE PTFE sealing ring?
The sealing ring made of PTFE has high chemical stability and chemical inertness, and its friction is small. Strong acid or strong oxidant and organic solvent have no effect on it; good thermal stability, cracking temperature is 400 Above °C, it has a wide operating temperature range and can work normally in the temperature range of -200 °C to 300 °C, without hardening damage in ultra-low temperature working environment.
Second, what kind of industrial machinery or environmental environment can the PTFE rubber seal be used in?
Modified PTFE rubber seals are widely used in the marine industry, aerospace industry, hydraulic and pneumatic systems, oil pipes in the petroleum industry, reciprocating and rotating shaft seals, and rubber elastomers to create combined seals or oil seals.
