<P>PROBLEM TO BE SOLVED: To provide a polyisocyanate composition allowing efficient production of polyurethane foams having a desired hardness, with little variations in the catalytic amount in a mixture of a polyol composition and a polyisocyanate composition, even in varying an isocyanate index, and to provide a raw material for producing polyurethane foams and a method for producing polyurethane foams. <P>SOLUTION: There is provided a polyisocyanate composition for producing polyurethane foams by reaction with a polyol in the presence of a catalyst, which includes a catalyst including at least one selected from the group consisting of tertiary amines, quaternary ammonium salts and organometallic compounds. A raw material for producing polyurethane foams is also provided which comprises the polyisocyanate composition and the polyol composition. A method for producing polyurethane foams is also provided which uses the polyisocyanate composition or the raw material for producing polyurethane foams. <P>COPYRIGHT: (C)2010,JPO&INPIT |
