Abstract
The polyurethane foam composition of the present invention comprises at least water, a catalyst, a surfactant, a polyisocyanate, and a polyol and/or a polymer-dispersed polyol in which polymer fine particles obtained by polymerizing a compound having an unsaturated bond are dispersed in a polyol, wherein the polyol comprises at least (A) a plant-derived polyol produced by using a raw material obtained from plants and (B) a low-monol polyol having an overall degree of unsaturation of 0.050 meq/g or less. The polyurethane foam relating to the present invention is obtained by foaming this polyurethane foam composition. The polyurethane foam contributes to reducing environmental burdens and attains hardness and ball rebound suitable for a cushioning material and excellent durability in a balanced manner.
