Abstract
"MéTODO PARA AUMENTAR A MACIEZ DA ESPUMA FLEXìVEL DE POLIURETANO EXPANDIDA EM áGUA, CO-AGENTE DE EXPANSãO PARA USO NO AUMENTO DA MACIEZ DA ESPUMA DE POLIURETANO FLEXìVEL EXPANDIDA EM áGUA, E, FORMULAçãO PARA USO NA PRODUçãO DE ESPUMA DE POLIURETANO FLEXìVEL, MACIA". é apresentado o uso de um HFC como o 134a como um co-agente de expansão para uso na produção de espumas de poliuretano flexíveis expandidas em água, as espumas tendo maciez melhorada."METHOD FOR INCREASING THE SOFTNESS OF FLEXIBLE POLYURETHANE FOAM EXPANDED IN WATER, EXPANSION CO-AGENT FOR USE IN INCREASING THE SOFTNESS OF FLEXIBLE POLYURETHANE FOAM EXPANDED IN WATER, AND, FORMULATION FOR USE IN FOAM PRODUCTION," . The use of an HFC such as 134a is presented as a co-blowing agent for use in the production of flexible polyurethane foams expanded in water, the foams having improved softness.
