Abstract: The invention relates to a method for producing polyurethane integral foam materials by reacting organic and/or modified organic polyisocyanates (a) with a polyetherol mixture (b) and chain extenders (c) in the presence of water and/or other expanding agents (e) and catalysts (f). The invention is characterized in that the polyetherol mixture (b) has a functionality of 2 to 3 and is comprised of: b1) at least one at least bifunctional polyetherol based on propylene oxide and/or butylene oxide and ethylene oxide with an ethylene oxide proportion of more than 40 % by weight with regard to the used total amount of alkylene oxide with an OH number ranging from 20 to 80 mg KOH/g and; b2) at least one at least bifunctional polyetherol based on propylene oxide and/or butylene oxide with an OH-number of less than 600 mg KOH/g and the reaction ensues with characteristic numbers of less than 110. The total weight of (b1) and (b3) is greater than the weight of (b2), and the proportion of chain extenders (c) is less than 15 % by weight with regard to the total weight of constituents (b) to (f). The invention also relates to polyurethane integral foam materials themselves that are produced according to this method, and to the use thereof for shoe soles, automobile safety parts and in vehicle manufacturing.
