The invention relates to a foamed polyurethane which is obtainable by mixing a) polyisocyanates, b) high-molecular compounds carrying groups that are reactive to isocyanate groups, c) solid particles, d) propellants, e) optionally chain extenders, cross-linking agents or mixtures thereof, f) optionally a catalyst and g) optionally other additives, to give a reaction mixture and allowing said mixture to react, the percentage of chain extenders being less than 6% by weight, based on the overall weight of components a) to f), the solid particle content being more than 15% by weight, based on the overall weight of components a) to f), and the average functionality of the high-molecular compounds carrying groups that are reactive to isocyanate groups being less than 2.5. The invention further relates to a molded body which contains a foamed polyurethane of the invention, to a method for producing the foamed polyurethane and to the use of a molded body according to the invention as a shoe sole. |
