    Abstract: A polyurethane foam is provided to prevent environment problem by using water as a foaming agent, to improve durability such as hydrolysis resistance and to reduce breakage, abrasion and scrach. A polyurethane foam comprises a polyol mixture 100.0 parts by weight having various functional groups and OH values; an isocyanate mixture 30~70 parts by weight having specific function; glycol 1~10 parts by weight having OH value of 1500~2500 mgKOH/g; butanediol 0.1~1.0 parts by weight having OH value of 500~1500 mgKOH/g; glycerol 0~5 parts by weight having OH value of 1500~2500 mgKOH/g; and water 0.01~4 weight% as a foaming agent based on the total weight of polyol.
