Polytetrafluoroethylene is widely used as a non-stick coating for cookware, such as frying pans and baking sheets, due to its excellent heat resistance and low friction properties. It is also employed in the manufacturing of seals, gaskets, and linings in industrial applications because of its chemical inertness and ability to withstand harsh environments. In the medical field, it is utilized for making implants and surgical devices, thanks to its biocompatibility and resistance to bodily fluids. Additionally, it is used in electrical insulation for wires and cables, as it provides high dielectric strength and thermal stability. Its water-repellent properties make it suitable for waterproof coatings in textiles and outdoor gear.
