Abstract

Se preparan espumas de poliuretano flexibles, de bajo olor, haciendo reaccionar poliisocianato organico y/u organico modificado (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), agentes a prueba de flama (f) y, si se requiere, asistentes adicionales y aditivos (g), mediante un proceso en el que la mezcla de polieterol (b) consiste de b1) cuando menos un polieterol difuncional u octafuncional basado en oxido de etileno y, si se requiere, oxido de propileno y/u oxido de butileno, que tiene un contenido de oxido de etileno de cuando menos 30% en peso, basado en la cantidad total de oxido de alquileno usada, y un numero OH de 2 0 a 200 mg KOH/g. y b2) por lo menos un polieterol basado en oxido de propileno y/o oxido de butileno y, si se requiere, oxido de etileno, que tiene un numero OH mayor de 20 mg KOH/g, el contenido de oxido de etileno siendo menor de 30% en peso, basado en la cantidad total de oxido de alquileno utilizada, y la espumacion se efectua en una escala de indice de menos de 150, el catalizador utilizado comprendiendo cuando menos un catalizador que soporta la reaccion de poliisocianurato. Las espumas de poliuretano flexibles preparadas de esta manera se utilizan como material para alfombra, tapiceria, asiento y de empaque y en el sector de higiene.
