Urethane foam, fire-resistant panel, and method for producing urethane foam

Abstract

To provide a urethane foam which exhibits superior fire resistance and thermal insulation, is light in weight, and is installable in partitions of buildings, to provide a fire-resistant panel, and to provide a method for producing a urethane foam.SOLUTION: A urethane foam is prepared by foaming a urethane resin composition comprising a polyol compound, a polyisocyanate compound, a blowing agent, an inorganic filler, a phosphate ester, a resinification catalyst, and a trimerization catalyst, wherein the urethane foam has a density of 65 to 200 kg / m3.SELECTED DRAWING: None
