<P>PROBLEM TO BE SOLVED: To provide a polyol composition for open-cell polyurethane foam, which can achieve all of the followings well-balancedly: (i) smoothness in a foam surface is improved by preventing the dripping caused when spraying the polyurethane foam, (ii) adhesiveness to an object to be sprayed is improved, and (iii) toughness of a foam and smoothness of a cutting surface of the foam are achieved. <P>SOLUTION: The polyol composition for open-cell polyurethane foam comprises, as polyol compounds: polyether polyol (A) that has an average functional group number of 2 to 4, has a weight-average molecular weight of 800 to 1,200, and is an alkylene oxide polymer; and polyether polyol (B) that has an average functional group number of 2 to 8, has a weight-average molecular weight of 300 to 800, and is the alkylene oxide copolymer. <P>COPYRIGHT: (C)2012,JPO&INPIT |
