| abstract |
The present invention relates to a process for preparing a polyurethane moulding with a density of from 150 to 350 g/l, in which a) polyisocyanate prepolymers obtainable from a polyisocyanate component (a-1), polyol (a-2), comprising polypropylene oxide, and chain extenders (a-3), b) polyetherpolyols with a functionality of greater than 2.0, c) polymer polyetherpolyols, d) chain extenders, e) catalysts, f) blowing agents comprising water, and optionally g) other assistants and/or additives are mixed to give a reaction mixture and hardened in a mould to give the polyurethane moulding. The present invention further relates to polyurethane mouldings obtainable by a process according to the invention, and to shoe soles comprising inventive polyurethane mouldings. |
