PTFE is a fluoropolymer possessing a unique combination of frictional, chemical, thermal, and electrical properties. It has a non-stick nature, is non-wetting and is self-lubricating. PTFE has outstanding chemical resistance and is unaffected by all known chemicals except alkali metals and under certain conditions, fluorine. PTFE has excellent weather resistance and has an extremely wide working temperature range. It is the best of the solid dielectrics and an excellent insulator.
This highly unique material was accidentally discovered by DuPont chemist, Roy Plunkett, in 1938, while he was working with Freon gasses. The residual powder that remained in the Freon canister after experimentation came to be known as Polytetrafluoroethylene (PTFE), later to be registered and patented by DuPont as Teflon® .Years later PTFE material would be used extensively in the industrialized world where its special characteristics are well-suited for the requirements of a vast assortment of applications.
Today PTFE resin is manufactured and trademarked worldwide by many chemical companies. Some of the more common names are:
Teflon® a registered trademark of E. I. du Pont de Nemours et cie.
Dyneon® a registered trademark of Dyneon
Polyflon® a registered trademark of Daikin
Algoflon® a registered trademark of Solvay Solexis
Without regard to what it is being called, the one thing that remains unchanged is that the simple name is PTFE.
