What is Polytetrafluoroethylene (PTFE)?
PTFE is a thermoplastic polymer that consists of carbon and fluorine atoms arranged in a chain-like structure. It is a synthetic polymer that was first discovered in 1938 by a DuPont chemist named Roy Plunkett. PTFE is most commonly known by the brand name Teflon, which is a registered trademark of Chemours Company FC, LLC.
Properties of Polytetrafluoroethylene
