PTFE(Polytetrafluoroethylene) is a fluoropolymer that is resistant to heat and chemicals. Because of its various properties, PTFE continues to be used in a wide range of innovative projects. It is possibly one of the most familiar mechanical plastic products applied today. Metal products coated with PTFE have a greater performance in various aspects.
