Patent ID: 8770666

Claim:
A molded urethane foam pad for vehicle seats comprising a polyurethane, wherein the pad is obtained by foaming and curing materials comprising a plant-derived polyol (A), a non-plant-derived polyol (B), water, a catalyst, a foam stabilizer and a polyisocyanate, and the pad has a core density of 55 to 65 kg/m 3 , and further wherein: the plant-derived polyol (A) is a polyol which is obtained by condensing a polyhydric alcohol of 6 hydroxyl groups with a plant-derived, C15 or higher hydroxycarboxylic acid and which has a hydroxyl value of 45 to 55 mg KOH/g, the non-plant-derived polyol (B) is a mixture of a polyol having a hydroxyl value of 18 to 26 mg KOH/g, and a polymer-dispersed polyol in which fine particles of a polymer of a compound having an unsaturated bond are dispersed in the polyol having a hydroxyl value of 18 to 26 mg KOH/g, the polyurethane contains a plant-derived molecular structure, the content of the plant-derived molecular structure is 15 to 20 wt % based on 100 wt % of the molded urethane foam pad and the content of a plant-derived component contained in the plant-derived polyol (A) is 14 to 19 wt % based on 100 wt % of the materials.
