(57) Abstract :
The present invention relates to foamed polyurethane obtainable by mixing a) polyisocyanates, b) relatively high molecular weight
compounds having groups reactive toward isocyanate groups, c) solid particles, d) blowing agents, e) if appropriate, chain extender,
crosslinking agent or mixtures thereof, f) if appropriate, catalyst and g) if appropriate, other additives to give a reaction mixture and
allowing the reaction mixture to react to completion, the proportion of chain extender being less than 6% by weight, based on the total
weight of the components a) to f), the content of solid particles being greater than 15% by weight, based on the total weight of the
components a) to f), and the average functionality of the relatively high molecular weight compounds having groups reactive toward
isocyanate groups being less than 2.5. The present invention furthermore relates to a molding comprising a foamed polyurethane
according to the invention, a process for the preparation of the foamed polyurethane according to the invention and the use of a
molding according to the invention as a shoe sole.
