摘要： The present invention provides flexible polyurethane foams with bulk densities less than about 15 kg/m3 and compressive strengths less than about 1.5 kPa and a process for producing these foams. The inventive foams are produced where polyisocyanates are reacted with special polyol mixtures in combination with high amounts of water and carbon dioxide dissolved under elevated pressure as the blowing agent.

摘要： A viscoelastic foam is produced by reacting (a) an isocyanate component that includes at least 25% by weight of diphenylmethane diisocyanate having a monomeric content of from 50 to 90% by weight, (b) an isocyanate-reactive component, (c) at least one catalyst, (d) at least one surface active agent, and (e) liquid carbon dioxide. These foams are characterized by a ball rebound of less than 20%. Particularly preferred foams are characterized by a 95% height recovery time greater than 4 seconds.
