<P>PROBLEM TO BE SOLVED: To provide a flexible polyurethane foam high in high flame retardancy and sufficiently low in resilience. <P>SOLUTION: The flexible polyurethane foam is such as to be obtained by crosslinking an isocyanate-terminated prepolymer with water, comprising a non-halogen-based flame retardant and an acrylic resin and being in 20% or less in resilience. It is preferable that the flexible polyurethane foam meet the following requirements: The non-halogen-based flame retardant is aluminum hydroxide, the content of this flame retardant is 45-80 mass% based on 100 mass% of the foam, and the density is 200-450 kg/m<SP>3</SP>. <P>COPYRIGHT: (C)2009,JPO&INPIT |
