Teflon (PTFE) – Material Description
Teflon is the brand name (by Chemours, formerly DuPont) for PTFE (Polytetrafluoroethylene), a high-performance fluoropolymer known for its exceptional non-stick properties, chemical resistance, and thermal stability.
It’s widely used in chemical processing, food equipment, electrical insulation, gaskets, and non-stick cookware.
