Conventionally, as a foam polyurethane material, for example, Patent Document 1 below has proposed a microcellular polyurethane elastomer produced by allowing a polyisocyanate compound to react with polyol, having an overall density of 100 kg/m3 or more, and having an overall density, a compression set, and a cell diameter on skin surface in specific relation.
Furthermore, as the foam polyurethane material, for example, Patent Document 2 below has proposed a polyurethane foam produced from materials including polyisocyanate including bis(isocyanatomethyl) cyclohexane, polyol, a blowing agent, and a catalyst.
