The present invention relates to a thermoplastic polyurethane (TPU-1) obtained or obtainable by the reaction of an isocyanate composition comprising MDI (IZ) with a polyol composition (PZ), wherein the polyol composition (PZ) is in the range from 900 to 2000 g/mol at least one polyol (P1) selected from polytetrahydrofuran having a phosphorus average molecular weight Mn, and the group consisting of 1,2-ethanediol, 1,3-propanediol, 1,4-butanediol and 1,6-hexanediol Thermoplastic polyurethane (TPU-1) comprising a chain extender (KV1) selected from; and hollow glass microspheres. The invention also relates to an outer shell of a ski shoe, preferably a ski boot, particularly preferably a ski boot, based on such a thermoplastic polyurethane and a method for producing a ski shoe. |
