PURPOSE:To obtain the title sheet capable of stamping molding, in high efficiency in a short cycle, into molded products with high impact resistance by incorporating a fibrous reinforcing material in a resin base material consisting of a thermoplastic polyurethane prepared by polymerization of a polymeric polyol and polyisocyanate. CONSTITUTION:The objective sheet can be obtained by incorporating a thermoplastic polyurethane prepared by polymerization between (A) pref. >=70mol% of at least one kind of polymeric polyol selected from a group of polyester polyols and polycarbonate polyols each containing alkane diol unit, derived from at least one kind of 8-10C alkane diol selected from a group of (methyl- substituted) 1,8-octanediol and 1,9-nonanediol and (B) a polyisocyanate (e.g. 4,4'-diphenylmethane diisocyanate) with (C) a fibrous reinforcing material. |
