Abstract: PURPOSE: A polyurethane foam composition is provided to show an excellent mechanical property including the repulsive elasticity, elongation, permanent compression set by using castor oil based polyol which is a reproducible bio polyol. CONSTITUTION: A polyurethane foam composition includes polyol and a diisocyanate mixture. The polyol comprises (a) polyol obtained by adding propylene oxides and ethylene oxides to glycerine, (b) polymer polyol obtained by adding propylene oxides and ethylene oxides to polyol, and (c) polyol obtained by adding ethylene oxides and propylene oxides to castor oil. The diisocyanate mixture comprises 60-90 weight% of 4,4'-diphenylmethanediisocyanate, and 10-40 weight% of 2,4-toluenediisocyanate, 2,6-tolurenediisocyanate or their mixture.
