ABSTRACT:
A process for producing a polyurethane foam which comprises mixing a polyol solution comprising 100 parts by weight of a polyester-polyol, 0.1 to 1.8 parts by weight of water and 0.1 to 5 parts by weight of urea, and a catalyst with a polyisocyanate compound and foaming the mixture. According to the process, there can be produced a polyurethane foam which satisfies both productivity and moldability even when having a low density, and is suitable for use in shoe soles.
