ABSTRACT:
Flame retardant flexible polyurethane foam compositions, methods of flame retarding flexible polyurethane foam compositions, articles made therefrom and flame retardants that comprise blends of tetrahalophthalate esters and phosphorus-containing flame retardant having at least about 5 wt. % phosphorus additives. The combined weight of the tetrahalophthalate ester and the phosphorus-containing flame retardant comprises about 5 to about 20% by weight of the flexible polyurethane foam compositions or reaction mixtures. The ratio of the tetrahalophthalate ester to the phosphorus-containing flame retardant is from about 80:20 to about 20:80 percent by weight and preferably from about 60:40 to about 40:60 percent by weight.
