Abstract:
1. A polyurethane foam obtained by reacting, foaming, and curing a raw material which comprises a polyol, a polyisocyanate, a blowing agent, a catalyst, and an inorganic compound hydrate, wherein the raw material contains, as the polyol, a polymeric polyol obtained by graft polymerization of a vinyl monomer onto a polyether polyol and a polyether polyol obtained by addition polymerization of an alkylene oxide to a polyhydric alcohol and having a mass average molecular weight of 400 to 1,000, wherein the blending quantity of the inorganic compound hydrate is 10 to 80 parts by mass per 100 parts by mass of the polyol, wherein the polyurethane foam has hot press moldability, and wherein the polyurethane foam has an apparent density of from 14 to 20 kg/m
