| description | Flame retardant, char-forming, flexible polyurethane foams are described which include, in addition to suitable diisocyanates and other basic foam-forming components, a flame retardant material and a polyol which has substantially non-reactive hydroxyl groups with respect to the diisocyanate component under the conditions of the foam-forming reaction. Accordingly, the polyol remains in the finished polyurethane foam substantially unreacted. When the finished foam product is subjected to combustion conditions the flame retardant material and unreacted polyol combine to retard flame formation and to provide a dripless char. In addition to the flame retardant and char-forming characteristics, the flexible polyurethane foam is firm, permitting the manufacture of clickable foams. |
