Polytetrafluoroethylene (PTFE) is a synthetic polymer known for its non-stick properties and high resistance to heat and chemicals. Commonly recognized by the brand name Teflon, PTFE is widely used in cookware, such as frying pans, to prevent food from sticking. It is also utilized in various industrial applications, including gaskets and seals, due to its durability. PTFE is made through the polymerization of tetrafluoroethylene, a gaseous compound. Its unique molecular structure gives it low friction and excellent electrical insulation properties. Additionally, PTFE is safe for food contact, making it a popular choice in the culinary world and beyond.
