ABSTRACT:
The present invention relates generally to polyisocyanate compositions for use in polyurethane thermoformable foams. The polyisocyanate compositions of the present invention which are also useful as binder/hardeners for prefoamed products offer improved stability at relatively low temperatures over other known polymeric diphenylmethane diisocyanate compositions.
