ABSTRACT:
Flexible polyurethane foam forming compositions comprising a polyether polyol, an organic isocyanate compound, a blowing agent, and a curing agent, preferably melamine, in an amount effective to rapidly cure the resultant foam and improve the compression set properties of the foam, the amount of curing agent generally ranging from about 0.25 up to about 4 parts by weight based on 100 parts polyether polyol. Also, the composition of polyurethane foams and methods of forming same from such foam-forming compositions.
