 (pŏl′ē-tĕt′rə-flo͝or′ō-ĕth′ə-lēn′, -flôr′-)
n.
A thermoplastic resin, (C2F4)n, that is resistant to heat and chemicals, has an extremely low coefficient of friction, and is used as a coating on cookware, gaskets, seals, and hoses.

polytetrafluoroethylene

(ˌpɒlɪˌtɛtrəˌflʊərəʊˈɛθɪˌliːn)
n
(Elements & Compounds) 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. Abbreviation: PTFE Also called (trademark): Teflon
