Abstract
Compositions and methods for providing a flexible flame retardant polyether polyurethane foam prepared from foam forming components of a polyether polyol, an organic isocyanate compound, water, a liquid phosphorus ester in an amount of about 4 to 10 parts by weight and melamine in an amount of 1 to 5 parts by weight, each based on 100 parts by weight of the polyether polyol in the composition. Between 15 and 500 percent by weight melamine is used to replace a minor portion of the amount of ester (i.e., less than half) which would normally be used to achieve substantially the same degree of flame retardance in the foam.
