ABSTRACT:
A process for preparing a predominately closed cell foam having an improved load bearing resiliency together with the improved polyurethane foam product, the process comprising co-reacting a fluid high-solids polymer/polyol and an organic polyisocyanate in the presence of an organo-tin catalyst, a tertiary amine catalyst, a blowing agent, a silicone-oxyalkylene surfactant and a critical amount of a filled diorganosilicone oil anti-foaming agent.
