ABSTRACT OF THE DISCLOSURE FLAME RETARDANT PHENOLIC FOAMS This invention relates to flame retardant phenol aldehyde foams which have a k value below 0.020 W/mk. The foams have as flame retardants a blend of a halosubstituted diphenyl oxide and an organic phosphorus compound. The feature of the invention is that unlike conventional flame retardants, the blend now used does not adversely affect the low k value i.e. the low thermal conductivity of the foam.
