A foamable reaction mixture comprising A) 100 % by weight of a polyol component consisting of a) 50 to 99% by weight, based on 100% by weight of component A), of castor oil, b) 0.9 to 49.9% by weight, based on 100% by weight of component A), of an isocyanate-reactive component, preferably a chain extending and/or a crosslinking component containing reactive hydroxyl groups, c) 0.1 to 5% by weight, based on 100% by weight of component A), of water, and, optionally d) auxiliary materials and/or additives, B) an isocyanate component, and, optionally C) inorganic fillers and/or reinforcing agents. The present invention also relates to foamed polyurethane molding produced by reacting A) with B), optionally in the presence of C), and to a process for the production of foamed polyurethane moldings based on these foamable reaction mixtures.
