Abstract

Un procedimiento para preparar espumas de poliuretano flexibles, que comprende las etapas de: (a) reunir un componente de poliol, un componente de poliisocianato, un agente de expansión que comprende dióxido de carbono líquido, un catalizador adecuado y, opcionalmente productos químicos auxiliares, a presión suficiente para mantener el dióxido de carbono en estado líquido, y (b) liberar la presión y permitir que la mezcla que se obtiene en la etapa (a) reaccione transformándose en una espuma de poliuretano flexible, en el que el componente de poliol comprende un poliol-polimérico que consta de, por lo menos, un poliéter-poliol que tiene una funcionalidad nominal media de, por lo menos 2,5 y lleva dispersas partículas de polímero en un nivel de entre 2 y 50% en peso sobre la base del peso total del poliol polimérico, con lo cual prácticamente ninguna de estas partículas de polímero tiene un tamaño que supere 50 micrómetros.
