Abstract
The polyurethanes processed through Reaction Injection Molding (RIM) span a wide range of mechanical properties and find their way in many and varied applications. The characteristics of such parts are large projected areas and intricate designs. Both are made possible by the injection of reactive liquid mixtures into the mold. Structural foam is produced by foaming the liquid and relying on the expansion of the mix to fill the mold after injection. The chemistry of urethanes then allows the full range of flexural moduli to be covered from rigids to elastomers. With structural foam, parts will have larger cross sections and demonstrate a composite structure. A thin dense skin covers the outer surfaces while the core is light and microcellular.
