TeflonThe coating, the English name TEFLON, is usually called because of the pronunciation.Teflon. It can be divided into four types: PTFE,FEP,PFA and ETFE. PTFE (polytetrafluoroethylene) non-stick coating can be used continuously at a high temperature of 260°C, and the maximum use temperature can reach 290-300°C. It has a very low coefficient of friction, good wear resistance and excellent chemical stability.

 TeflonMaterial products are often collectively referred to as "non-stick coatings"; it is a synthetic polymer material that uses fluorine to replace all the hydrogen atoms in polyethylene. The material is resistant to acids, alkalis and various organic solvents, and is almost insoluble in all solvents. At the same time, PTFE has the characteristics of high temperature resistance and its friction coefficient is extremely low, so it can be used as a lubrication method and has become an ideal coating for non-stick pans and water pipes.
