<p>Disclosed is a low-resilience flexible polyurethane foam which is composed of a flexible polyurethane foam obtained by reacting and foaming a mixed liquid containing (A) an organic polyisocyanate, (B) a polyol, (C) a chain extender, (D) a catalyst and (E) a foaming agent. The flexible polyurethane foam has a density within the range of 65-95 kg/m3, and the organic polyisocyanate (A) contains, per 100% by mass of the organic polyisocyanate (A), 52.5-62.5% by mass of diphenylmethane diisocyanate, 16.5-38.5% by mass of polymethylene polyphenylene polyisocyanate, and 9.0-21.0% by mass of carbodiimide-modified diphenylmethane diisocyanate.</p> |
