FIELD: facing materials for pipes, pumps, elastic films, working wheel of centrifugal pump, or the like. SUBSTANCE: composition comprises, wt %: component (A), i.e. tetrafluoroethylene homopolymer or perfluorotype copolymer thereof having from 2•102 to 1•105 methylol groups per 1•106 carbon atoms in end group and nw from 5•102 to 5•105, 1-50; component (B), i.e. liquid crystalline polyether and component (E), i.e. tetrafluoroethylene homopolymer or perfluorotype copolymer thereof having no methylol groups in end group or having less that 2•102 methylol groups per 1•106 carbon atoms. Variant of invention is composition comprising in component (C) compound selected from group consisting of polytetrafluoroethylene- hexafluoropropylene copolymer and tetrafluoroethylene- perfluoroalkylvinyl ether copolymer having no methylol groups in end group per 1•106 carbon atoms. Molded products having improved moldability, stability of sizes, deformation resistance and mechanical properties are prepared on the basis of components. EFFECT: improved properties of the thermoplastic composition. 12 cl, 8 ex, 2 tbl
