Beschreibung
Zusammenfassung:	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 produce d where polyisocyanates are reacted with special polyol mixtures in combinatio n with high amounts of water and carbon dioxide dissolved under elevated pressure as the blowing agent.
