Polytetrafluoroethylene (Teflon or PTFE), commonly known as "Plastic King", Chinese trade names "Teflon", "Teflon", "Teflon", "Teflon" and so on. It is a polymer compound obtained by polymerizing tetrafluoroethylene, which has excellent chemical stability, corrosion resistance, sealing property, high lubrication and non-stickiness, electrical insulation and good aging resistance. It can work for a long time at a temperature of +250 ° C to - 180 ° C. In addition to molten metal sodium and liquid fluorine, it can withstand all other chemicals and does not change in aqua regia. Used as engineering plastics, it can be made into PTFE tubes, rods, strips, plates, films, etc. Generally used in corrosion-resistant pipes, containers, pumps, valves, and radar, high-frequency communication equipment, radio equipment, etc. with high performance requirements.
Simply put, PTFE is better than nylon in corrosion resistance and high temperature resistance. The wear resistance of nylon is better than that of polytetrafluoroethylene. The price of PTFE is more expensive than nylon.
