Description
Strictly speaking, the PTFE o-rings or Teflon o-rings are not rubber o-rings, but plastic o-rings. PTFE, also called Teflon, commonly known as “Plastic King”, is a high molecular polymer obtained by polymerizing tetrafluoroethylene as a monomer. White waxy, translucent, excellent heat and cold resistance, can be used for a long time at -100 ~ 280 ºC.
This material has the characteristics of acid and alkali resistance and resistance to various organic solvents and is almost insoluble in all solvents. At the same time, polytetrafluoroethylene has the characteristics of high-temperature resistance, and its friction coefficient is extremely low, so it can be used for lubrication, and it has also become an ideal coating for easy cleaning of the inner layer of water pipes.
