Abstract: Rigid, closed-cell polyurethane foams are produced by a RIM process by reacting an organic polyisocyanate with an isocyanate-reactive mixture in which a significant amount of a bio-based polyol is present. The foams produced by this process are characterized by improved heat sag and heat distortion temperature.
