  • Publication number: 20090192237
    Abstract: A flame retardant composition for use in flame retarding a polyurethane foam composition so that the foam has reduced scorch as a result of its manufacture, said flame retardant composition comprising a mixture of (a) a flame retardant of the type that normally causes scorch when used in such foam and (b) a benzofuranone derivative, as a anti-scorch stabilizer. Flame retarded polyurethane foams having reduced discoloration are also provided.

  • Publication number: 20090012192
    Abstract: Flame retarded, colored polyurethane foam compositions having reduced discoloration, said foam compositions comprising a foam, which is the reaction product of a polyol and an isocyanate, a colorant, a flame retardant of the type that normally causes scorch and a benzofuranone derivative, as an anti-scorch stabilizer.

  • Patent number: 7288577
    Abstract: A polyurethane foam can be flame retarded by the incorporation therein of a flame retardant blend that comprises: (a) a non-oligomeric non-halogenated organophosphorus flame retardant (e.g., a phosphate ester) that is adapted for use in a polyurethane foam formulation; and (b) an oligomeric organophosphorus flame retardant (e.g., a phosphate ester) having a phosphorus content of no less than about 10%, by weight, and at least three phosphate ester units therein.

  • Publication number: 20050222284
    Abstract: Flame-retardant blends are described that comprise: (a) a monomeric halogenated organic flame-retardant, which is adapted for use in a polyurethane foam formulation; and (b) an organic phosphate flame-retardant. The organic phosphate flame-retardant has the formula: where Ar is an aryl or an alkaryl group, R represents an alkylene or arylene group, and the average value of n is 0 to 5. In addition, an organic brominated additive can be selected in combination with the phosphate ester. These flame-retardants are incorporated into flexible polyurethane foams at various densities.

  • Publication number: 20040024097
    Abstract: A flame retardant blend is disclosed that comprises: (a) a monomeric halogenated organic flame retardant that is adapted for use in a polyurethane foam formulation; and (b) an oligomeric organophosphate flame retardant having a phosphorus content of no less than about 10%, by weight, and at least three phosphate ester units therein, the amount of (a) in the blend being no less than the amount of (b). It is useful in polyurethane foams.
