Poly tetrafluoroethylene
WebPolytetrafluoroethylene. In chemistry, polytetrafluoroethylene ( PTFE) is a synthetic fluoropolymer which finds numerous applications. PTFE's most well known trademark in the industry is the DuPont brand name Teflon . PTFE has an extremely low coefficient of friction and is used as a non-stick coating for pans and other cookware. WebA fluoropolymer is a type of polymer that consists of carbon and fluorine molecules, and the main constituent of polytetrafluoroethylene is tetrafluoroethylene (TFE), which is a member of the fluorocarbon family. The most notable attribute of PTFE is that, due to its low dielectric constant, it is entirely hydrophobic, which means that water ...
