What is the characteristics of a polytetrafluoroethylene (PTFE) seal? Teflon shaped seals, also known as PTFE seals or Teflon seals, referred to as PTFE or F4, are polymers of tetrafluoroethylene. The modified PTFE shaped 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, and has been obtained in the hydraulic sealing system. A wide range of applications.

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.

What industrial machinery or environment can PTFE seals be used in? Dongguan Teflon rotary seal manufacturer modified PTFE shaped rubber seals are widely used in the weapon industry, aviation industry, hydraulic and pneumatic systems, oil pipelines in the petroleum industry, reciprocating and rotating shaft seals, and rubber elastomers. Combine to make a combination seal or oil seal.
