Abstract:
1. A flexible polyurethane foam obtained by reacting and molding in a closed mold a high molecular weight polyoxyalkylene polyol or a polymer-dispersed polyol comprising fine polymer particles in the high molecular weight polyoxyalkylene polyol, with a polyisocyanate compound, in the presence of a catalyst, a blowing agent consisting of water, a foam stabilizer, and an amino-modified silicone (F), wherein the amino-modified silicone (F) is present in an amount of from 0.00001 to 0.005 part by mass per 100 parts by mass of all active hydrogen compounds wherein the amino-modified silicone (F) is a compound represented by the following formula (1) or (2): provided that in the formula (1), R 1 is a C 1-10 alkylene group, R 2 is a C 1-10 alkyl group, and k is an integer of from 1 to 2,000, and in the formula (2), m is an integer of from 0 to 100; n is an integer of from 1 to 2,000; each of R wherein said high molecular weight polyoxyalkylene polyol has an unsaturation value of at most 0.07 meq/g, wherein the high molecular weight polyoxyalkylene polyol has an average number of hydroxyl groups of from 2 to 6, wherein the high molecular weight polyoxyalkylene polyol has a molecular weight per hydroxyl group of from 1,000 to 5,000, and wherein with respect to a foam obtained by foaming into a thickness of 100 mm, the 25% hardness (ILD) X (N/314 cm
