Polyurethane foam and interior material

Abstract

[Problem] To provide a technology for producing a polyurethane foam which exhibits excellent physical properties despite containing a high degree of biomass. [Solution] The present technology provides a polyurethane foam obtained from a composition containing a polyol and an isocyanate, wherein said polyol contains a plant-derived polyol and a polyether polyol which has a number-average molecular weight of 3,000 or more and is obtained by the addition polymerization of only propylene oxide (PO) with an initiator.
