Abstract

Se preparan espumas de poliuretano flexibles haciendo reaccionar poliisocianatos organicos y/u organicos modificados (a) con una mezcla de polieterol (b) y, si se requiere compuestos adicionales (c) que tienen atomos de hidrogeno reactivos hacia isocianatos en presencia de agua y/u otros agentes de soplado (d) catalizadores (e) y, si se requiere, asistentes adicionales y aditivos (f), mediante un proceso en el que la mezcla de polieterol (b) consiste de b1) cuando menos un polieterol que es por lo menos difuncional, tiene un numero OH de 20 a 100 mg KOH/g y se basa en oxido de propileno y/u oxido de butileno y oxido de etileno, que tiene un contenido de oxido de etileno de mas de 40% en peso, basado en la cantidad total de oxido de alquileno utilizada, y si se requiere, polieteroles adicionales que son cuando menos difuncionales, estan basados en oxido do propileno y/u oxido de butileno y oxido de etileno y tienen un numero OH de 20 a 160 mg KOH/g y b2) cuando menos un polieterol difuncional a hexafuncional basado en oxido de propileno y/u oxido de butileno y que tiene un numero OH de menos de 800 mg KOH/g y las espumas se preparan con indices de menos de 110, la cantidad en peso de (b1) siendo mayor que aquella de (b2). Las espumas de poliuretano flexibles preparadas mediante este proceso se utilizan para propositos de tapiceria, y propositos de aislamiento, en construccion de vehiculos y en el sector medico y de higiene.
