The present invention relates to a method for producing a polyurethane elastomer, comprising the reaction of at least one isocyanate composition (ZI) with a polyol composition (ZP) which contains a poly-ε-caprolactone polyol that is obtainable or obtained by reacting ε-caprolactone and a starter molecule selected from the group consisting of diols having a number-average molecular weight in the range of 80 to 1500 g/mol, thereby obtaining a isocyanate-group-containing prepolymer, and the reaction of the prepolymer obtained in step (i) with at least one chain extender (KV), the polyol composition (ZP) containing α-hydro-ω-hydroxypoly(oxytetramethylene) polyols in an amount in the range of 0 to 1 wt.% relative to the total polyol composition. The present invention further relates to a polyurethane elastomer obtainable or obtained according to a method according to the invention and to the use of a polyurethane according to the invention or of a polyurethane elastomer obtainable or obtained according to a method according to the invention for producing a molded article, especially a damping element, shock absorber or buffer stop or of a part of a shoe or a shoe sole, for example an insole or midsole. |
