Polytetrafluoroethylene, commonly known as PTFE, is a synthetic polymer made from the polymerization of tetrafluoroethylene. It is best known for its non-stick properties, making it a popular choice for cookware coatings, such as frying pans. PTFE is also highly resistant to heat, chemicals, and electrical conductivity, which makes it useful in various industrial applications. In addition to cookware, PTFE is used in gaskets, seals, and insulation for wires and cables. Its low friction properties make it ideal for applications in machinery and automotive parts. Overall, PTFE is valued for its durability and versatility in many fields.
