Zusammenfassung
(EN) The present invention relates to a process for producing polyurethane foam moldings where the density of the molding is at most 500 g/L, by mixing the following to give a reaction mixture: a) organic polyisocyanates with b) polyesterols, c) blowing agents, d) cell-opening additives selected from the group consisting of homo- or copolymers based on ethylhexyl acrylate, on polybutadiene, on polyisobutene, and on diorganosilicones, or a mixture of two or more of said antifoams, e) silicone-based cell stabilizers and optionally f) chain extenders and/or crosslinking agents, g) catalysts, and h) other auxiliaries and/or additives, and charging the materials to a mold, and permitting them to complete a reaction to give a polyurethane foam molding. The present invention further relates to polyurethane moldings obtainable by this process, and to the use of said moldings as shoe sole, steering wheel, seat, or armrest.
