PROBLEM TO BE SOLVED: To obtain a flexible polyurethane foam which has a high shock- absorbing property and can keep good sense of touch around room and low temperatures, and is useful as an interior material for car by reacting an organic polyisocyanate with a specific polyol and so on, followed by foaming so as to have specific properties. SOLUTION: This foam is obtained by reacting (A) an organic polyisocyanate component (e.g. diphenylmethanediisocyanate) with (B) a polyol component consisting of a polyoxyalkylenepolyol having an average functional group number of 2-8 and a hydroxyl equivalent of 900-3,300 and (C) a compound represented by the formula ((n), (x), and (y) are each 0-20; x+y=0 to 20) (preferably, nonlyphenol) at a C/B ratio of 0.00005-0.001 mol/g, followed by foaming so as to have a repulsion elasticity of 30% or smaller and a compression load temperature dependence of 0.030 kg/cm2 or smaller as expressed by the difference between 25% compression load values at -20 deg.C and 20 deg.C. |
