What are the characteristics of PTFE Teflon (Teflon)? Teflon (Teflon) has the characteristics of acid and alkali resistance, resistance to 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 for lubrication, and it has also become an ideal coating for non-stick pans and the inner layer of water pipes.The mechanical strength of PTFE is slightly lower than that of other plastics, but its mechanical properties can be effectively strengthened by adding composite materials such as glass fiber, carbon fiber or copper fiber. PTFE, FEP, PFA, and ETFE play the best functions in various environments.PTFE has excellent temperature resistance, chemical resistance, and drug resistance. Its melting point is 327°C, and it can be used at extremely low temperatures down to minus 170°C. It is an excellent heat-resistant material.It will not react to concentrated sulfuric acid and boiled aqua regia. In various extremely harsh environments, PTFE, FEP, PFA, and ETFE will be excellent application materials
