ABSTRACT:
Flexible, slabstock polyurethane foam compositions useful for a rapid-cool process are disclosed. The foams are produced in the presence of a tetravalent tin catalyst, preferably at a relatively low isocyanate index, and preferably with a polyol that contains a non-volatile inhibitor. The foams of the invention eliminate or greatly reduce the amount of visible smoke produced in a rapid-cool process.
