(EN) The present invention relates to a method for producing polyurethane molded foam bodies having a molding part density of not more than 500g/L wherein (a) organic polyisocyanates are mixed with (b) polyesteroles (c) expanding agents (d) cell opening additives selected from the group consisting of homo or copolymers on the basis of ethylhexylacrylate polybutadiene polyisobutene and diorganosilicones or mixtures of two or more of these defoamers (e) silicone based cell stabilizers and optionally (f) chain lengthening agents and/or cross linking agents (g) catalysts and (h) other auxiliary agents and/or additives to form a reaction mixture are introduced in a mold and allowed to fully cure to form a polyurethane molded foam body. The present invention further relates to polyurethane molded bodies obtained by such a method and to the use of said molded bodies as a shoe sole steering wheel seat or armrest.
