Abstract

Process for preparing non-flexible cellular polyurethanes having at least 80% of open cells, by reacting a polyol with a polyisocyanate in the presence of water, characterized in that a composition consisting of 30 to 70% composed polyols in weight of the mixture of at least one polyether polyether having a hydroxyl number of 350 to 600 and a functionality of at least 3, and 30 to 70% by weight of the mixture of a polyether polyol, at least, having a hydroxyl number of 30 to 225 and a functionality of 2 to 4, whose composition has an average hydroxyl number of 175 to 350 and an average functionality of 3 to 8, is mixed with enough polyisocyanate to provide an NCO ratio : OH greater than 0.9: 1; and with 1 to 8% water, based on the weight of the polyol mixture.
