    • The present invention relates to lightfast and hydrolytically resistant molded polyurethane parts with excellent strength properties and a high temperature resistance and colorfastness to light at elevated temperatures for sophisticated applications in the sector of automobile interiors, which products are produced from a reaction mixture of aliphatic and/or cycloaliphatic compositions by using a cost-effective reaction injection molding method (RIM) or a casting method that requires only a short mold residence time. To this end, A) a composition composed of A1) an OH-terminated trifunctional prepolymer, A2) a polyol or a polyol combination, A3) at last one di- and/or trifunctional chain-lengthening agent and/or crosslinking agent with amine and/or hydroxyl groups, and A4) a catalyst system, and optionally A5) a stabilizer system, and optionally A6) at least one additive, and B) an isocyanate composition, are reacted.
