<P>PROBLEM TO BE SOLVED: To provide a resin composition for forming a flexible polyurethane foam, which is excellent in compatibility of a polyol compound liquid and storage stability, and is excellent in stability during foaming, and has a low closed cell ratio and a small compression set, and is excellent in thermal adhesiveness and high frequency welding properties (initial peeling strength, final peeling strength). <P>SOLUTION: The resin composition for forming a flexible polyurethane foam includes a polyhydroxy compound (A), a polyisocyanate (B) and an organic phosphorus compound. A polyoxyalkylene glycol (a1), a polyester polyol (a2) obtained by using polyvalent alcohol having a main chain with side chain and having a weight average molecular weight of 700-1200, and a polyester polyether block copolymer (a3) are essentially used in combination as components used for the (A), wherein the mixing ratio of (a1), (a2) and (a3) is (a1)/(a2)/(a3)=94/1/5 to 58/12/30 mass ratio. <P>COPYRIGHT: (C)2012,JPO&INPIT |
