A Thermoplastic RIM System for Automotive Fascia 760332

A thermoplastic polyurethane has been developed which can be processed by reaction injection molding and which can be recycled as necessary by injection molding. An MDI-based quasi-prepolymer was developed specifically for this material. The properties meet specifications for automotive fascia, including painted bumperette impact and paint adhesion. The effect of postcure is to improve both high and low temperature properties. It is recommended that part weight reduction be achieved by using thinner wall thicknesses.
