  • Low Scorching Flame Retardants for Colored Polyurethane Foams
    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.

  • Dialkyl dicarbonates as blowing agents for polymers
    Patent number: 5030664
    Abstract: The present invention pertains to a composition of matter and to a method of using the composition to produce foamed plastics, wherein a major, auxiliary source of blowing agent for the foam is the decomposition of dialkyl dicarbonates. The dialkyl dicarbonates can be decomposed over temperatures ranging from about 10.degree. C. to about 45.degree. C. when used in combination with particular tertiary amine decomposition catalysts.
    Type: Grant
    Filed: December 4, 1990
    Date of Patent: July 9, 1991

  • Method of preventing scorch in a polyurethane foam and product thereof
    Patent number: 4547528
    Abstract: Incorporation of from about 0.001% to about 5% of a mixture of an N-alkanoyl-N,N'-dialkyl-phenylenediamine compound (e.g. N-heptanoyl-N,N'-di-sec-butyl paraphenylenediamine) and a fluorescent brightener (e.g., a bis(benzoxazole) substituted thiophene) in a flame retarded polyurethane foam formulation stabilizes the formulation against scorching as the foam is formed therefrom.

  • Method of preventing scorch in a polyurethane foam and product thereof
    Patent number: 4544680
    Abstract: Incorporation of from about 0.01% to about 5% of an N-alkanoyl-N,N'-dialkyl-phenylenediamine compound (e.g. N-heptanoyl-N,N'-di-sec-butyl-para-phenylenediamine) in a flame retarded polyurethane foam formulation stabilizes the formulation against scorching as the foam is formed therefrom and also improves the indentation load deflection of the foam.

  • Polyester polyurethane foam based medical support pad
    Patent number: 4535096
    Abstract: A polyester polyurethane foam formulation useful in medical pads to support bedridden patients is described. The foam is formed by reaction of a polyester polyol, isocyanate and blowing agent combination of water and halogenated hydrocarbon auxiliary blowing agent. A halogenated flame retardant, e.g., an organophosphorus compound, is present. A liquid char forming and dripping ember retardant additive is also present.

  • Method of evaluating scorch in flexible polyurethane foam
    Patent number: 4131660
    Abstract: A method of evaluating the probability of scorch in flame retarded flexible polyurethane foam without preparing a large quantity of foam is described. A microwave oven is utilized to heat a foam sample pursuant to the invention. The method is useful to predict the probability that flame retarded foam will scorch on curing and therefore can be used to avoid damage to large commercial quantities of foam. The method can also be used to screen flame retardants for polyurethane foams.
