|PTFE, Also called (trademark): Teflon a white thermoplastic material with a waxy texture, made by polymerizing tetrafluoroethylene. It is nonflammable, resists chemical action and radiation, and has a high electrical resistance and an extremely low coefficient of friction. It is used for making gaskets, hoses, insulators, bearings, and for coating metal surfaces in chemical plants and in nonstick cooking vessels|
|polytetrafluoroethylene (pŏl'ē-tět'rə-flr'ō-ěth'ə-lēn', -flôr'-) Pronunciation Key
A synthetic polymer consisting of a chain of fluorinated ethane units (C2F4). It is a thermoplastic resin that is resistant to heat and chemicals and has an extremely low coefficient of friction (resistance to objects sliding over its surface). It is used as a coating on cookware, gaskets, seals, and hoses.
