Abstract: Preparation of a polyurethane foam (I) with a density of 70-300 g/dm 3>and 1-20 cells/cm, comprises mixing and reacting polyisocyanate obtained by reacting diisocyanates e.g. methanediisocyanate, with non-polar polyetherols obtained by alkoxylation of 2 to 4-hydric alcohols with propylene oxide and/or butylene oxide, and/or polytetrahydrofuran, and polar polyetherols obtained by alkoxylation of 2- to 4-hydric alcohols with ethylene oxide and propylene oxide, a blowing agent comprising water, and optionally chain extenders, a catalyst, and other auxiliaries and/or additives to form (I). Preparation of a polyurethane foam (I) with a density of 70-300 g/dm 3>and 1-20 cells/cm, comprises mixing and reacting polyisocyanate obtained by reacting diisocyanates comprising methanediisocyanate and/or naphthalene diisocyanate, with non-polar polyetherols obtained by alkoxylation of 2 to 4-hydric alcohols with propylene oxide and/or butylene oxide and/or polytetrahydrofuran, and polar polyetherols obtained by alkoxylation of 2- to 4-hydric alcohols with ethylene oxide and propylene oxide, where the proportion of oxyethylene units, based on all oxyalkylene units, is at least 15 wt.%, and the isocyanate content of the polyisocyanate is 3-14%, a blowing agent comprising water, and optionally chain extenders, a catalyst, and other auxiliaries and/or additives to form (I) An independent claim is included for the polyurethane foam made by the method.
