Abstract

Procedimiento de fabricación de espumas flexibles de poliuretano de alta elasticidad, en ausencia de compuestos tenso activos que resultan de la condensación de óxidos de alquileno sobre siloxanos, a partir de poli isocianatos orgánicos, de catalizadores aminados exclusivamente, de agentes de expansión y de poliéteres hidroxilados que resultan de la poliadición de óxido de propileno y de óxido de etileno sobre uno o varios compuestos que contiene átomos de hidrógeno móvil, caracterizado porque los piliéteres hidroxilados se obtienen a partir de compuestos que contienen dos átomos de hidrógeno móvil y que poseen: un índice de hidróxilo comprendido entre 20 y 40 y, preferentemente entre 25 y 35, una proporción de grupos que proceden de la poliadición del óxido de etileno comprendida entre 10 y 50% en peso y, preferentemente, comprendida entre 15 y 30% en peso del conjunto de los grupos que proceden de la poli adición del óxido de etileno y del óxido de propileno y una proporción de grupos hidróxilo primario comprendida entre 60 y 100% y, preferentemente entre 75 y 90% con respecto al conjunto de los grupos hidróxilo.
