Blends of tetrahalophthalate esters and phosphorus-containing flame retardants for polyurethane compositions

摘要

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.
