  • Publication number: 20150266993
    Abstract: The present disclosure provides a flame retarded slabstock polyurethane foam composition for flame lamination, which does not need to add a separate flame retardant additive because the polyurethane itself has flame retardancy. The flame retarded slabstock polyurethane foam composition for flame lamination according to the present disclosure, wherein the foam itself has flame retardancy by comprising methylene diphenyl diisocyanate (MDI), polymethylene diphenyl diisocyanate (PMDI), or a mixture thereof as an isocyanate compound, thereby obtaining an epochal effect that it does not need to add a separate flame retardant and an effect of solving a problem that physical properties of the conventional flame retarded slabstock polyurethane foam composition are reduced by adding a flame retardant.
