PURPOSE:To obtain the title film excellent in lubricity, heat resistance and mechanical properties by thermoforming a composition prepared by mixing a specified polyether copolymer with an inorganic filler in a specified mixing ratio. CONSTITUTION:This film is prepared by thermoforming a composition prepared by mixing a polyether copolymer comprising repeating units of formulas I and II and having a content of repeating units of formula I of 0.15-0.4 [in terms of a molar ratio: I/(I+II)] and a melt viscosity at 400 deg.C (at a zero shear rate) of 3000-100000P with 0.001wt.% or above inorganic filler (e.g. talc). |
