  • 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.

  • Flame retarded polyurethane foams with improved color qualities
    Patent number: 4130513
    Abstract: The color qualities of low density polyurethane foams produced with certain flame retardants is improved by reducing scorch through incorporation of a mixture of diphenyl p-phenylenediamine and the reaction product of diphenylamine and acetone into the foam. The mixture can be employed by admixing with the flame retardant from about 0.5 to about 5.0 percent of said mixture by weight of the flame retardant. The weight ratio of diphenyl p-phenylenediamine to the reaction product of diphenylamine and acetone is from about 1:20 to about 20:1.
