Abstract

Se preparan espumas de poliuretano flexibles reticuladas haciendo reaccionar poliisocianatos organicos y/u organicos modificados (a) con una mezcla de polietarol (b) y, si se requiere, compuestos adicionales (c) que tienen atomos de hidrogeno reactivos hacia isocianatos, en presencia de agua y/o otros agentes de soplado (d), catalizadores (e) asistentes adicionales y aditivos ( f), mediante un proceso en el que la mezcla de polieterol (b) comprende b1) cuando menos un polieterol di funcional o polifuncional que tiene un numero OH de 20 a 150 mg KOH/g, basado en oxido de propileno y/u oxido de butileno y oxido de etileno y que tiene un contenido de oxido de etileno de mas de 40% en peso, basado en la cantidad total de oxido de alquileno usado, (b1.1 ) y, si se requiere, polieteroles difuncionales o polifuncionales adicionales que tienen un numero OH de 20 a 150 mg KOH/g, basado en oxido de propileno y/u oxido de butileno y oxido de etileno y que tiene un contenido de oxido de etileno de no mas de 40% en peso, basado en la cantidad total de oxido de alquileno usada, que tiene un contenido de grupos OH primarios de mas: de 40%, (b1.2), con cantidades totales del componente (b1) de cuando menos 70% en peso, basado en el peso total del componente (b), (b1.1) estando presente en cantidades de cuando menos 50% en peso, basado en el peso total del componente (b), y b2) cuando menos un polieterol difuncional o polifuncional basado en oxido d e propileno y/u oxido de butileno y que tiene un numero OH de mas de 25 mg KOH/g en cantidades de no mas de 30% en peso, basado en el peso total del componente (b), y estabilizadores de silicona se utilizan en cantidades de 0.02 a 5% en peso, basado en el peso total de los componentes (b) a (f). Las propias espumas de poliuretano flexibles reticuladas preparadas de esta manera se utilizan para propositos de tapiceria. para relleno de cavidad y como medio de soporte y medio de filtro.
