A polyurethane foam for shoe soles having an average density of 0.15 to 0.5 g/cm3, prepared by reacting polyol components comprising (A) a polyether-polyol A having two or more hydroxyl groups; (B) a polymer-polyol B comprising a polyether-polyol having two or more hydroxyl groups as a base material and fine polymer particles; and (C) a chain extender, with a polyisocyanate compound in the presence of a blowing agent and a catalyst, wherein the amount of the fine polymer particles is 10 to 30 parts by weight, based on 100 parts by weight of a total amount of the polyether-polyol A and the polymer-polyol B. The polyurethane foam has no peeling of a skin layer, and no foam shrinkage, and is excellent in appearance. Therefore, the polyurethane foam can be desirably used as shoe soles. |
