About PTFE

Polytetrafluoroethylene (PTFE) is a high-performance synthetic fluoropolymer renowned for its exceptional resistance to heat, chemicals, and electrical conductivity. Known widely by its trade name “Teflon™,” PTFE was developed in the 1930s and has become integral in various industries due to its unique properties. With its low friction, non-stick surface, and non-reactive nature, PTFE is invaluable in sectors ranging from aerospace to food processing, offering reliable solutions for challenging environments.
