/ˌpɒlɪtɛtrəˌflɔːrəʊˈɛθᵻliːn/, U.S.

/ˈˌpɑliˌtɛtrəˌflʊroʊˈɛθəˌlin/

Forms: see poly- comb. form and tetrafluoroethylene n.

Origin: Formed within English, by compounding. Etymons: poly- comb. form, tetrafluoroethylene n.

Etymology: < poly- comb. form + tetrafluoroethylene n. Compare slightly earlier Teflon n.

Chemistry.

A polymer of tetrafluoroethylene; esp. a tough, crystalline, chemically inert, thermally stable material that has a low coefficient of friction and is used as a moulding material and as a coating for bearings, non-stick cooking utensils, etc. Abbreviated PTFE.A proprietary name for this material is Teflon n.
