Abstract

Procedimiento para la obtención de materiales espumados endurecedores en frío, flexible conteniendo grupos uretano, caracterizado porque se hacen reaccionar poliéteres que llevan como mínimo dos grupos hidroxilo, del peso molecular 400-10.000. donde como mínimo un 10% e peso de los grupos hidroxilo existentes representan grupos hidroxilo primarios, con una mezcla de difenilmeta-diisocianatos y polifenol-polimetilen-poliisocianatos oligómeros, que contienen un 60-90% en peso, preferentemente un 65-80% en peso 4,4'-difenilmetan-diisocianato y un 3-30% en peso, preferentemente un 10-30% en peso de 2,4'-difenilmetan-diisocianato, en presencia de agentes de propulsión y, en caso dado, en presencia de catalizadores y ulteriores agentes auxiliares de la espumación.
