Moldings based on polyurethane binders containing at least one polyisocyanate, at least one polyol or polyamine, at least one carboxylic acid such as a long-chain fatty acid, and, if appropriate, water and/or one or more amines with one or more fillers have high flexibility if the average particle diameter of the fillers is up to 2.5 mm. The fillers preferably contain particles having round, oval or completely irregular structures. The binder composition and the fillers are reacted at a pressure of 1 MPa to 40 MPa (preferably, at temperatures of from about 60 to about 180° C. for from about 1 to 30 min), and then the shaping apparatus is depressurized. The resultant moldings are suitable for the production of sheets or of semifinished products for the coating of furniture, kitchen worktops, floors, walls, stairs, or ceilings. |
