PTFE (Polytetrafluoroethylene) sheet and rod, also known as Teflon, is a kind of high polymer prepared by polymerization of tetrafluoroethylene as the monomer. With excellent heat and cold resistance, excellent chemical resistance, outstanding electrical insulation, and an extremely low coefficient of friction. Widely used in chemical processing, electronics, mechanical engineering, and food industries. Also has the characteristics of acid and alkali resistance, resistance to various organic solvents, and is almost insoluble in all solvents, the use temperature is -80 to 260ºC.
