Commercialized use of the reaction injection molding (RIM) process first involved polyurethane elastomers. Improvements to this RIM elastomer system were soon made by the use of a new aromatic-amine chain extender, diethyltoluenediamine (DETDA). New insights on the commercial usefulness of RIM elastomers were provided by these new systems classified as polyurethane/urea RIM elastomers. Recently, a further refined system has begun to make strong headway in the RIM elastomer market. Amine-terminated polyether resins along with the amine chain extender are incorporated into these systems which are referred to as polyurea RIM elastomer. Polyurea RIM elastomer systems, which require no catalyst, are extremely fast and capable of high productivity. Incorporation of internal mold release agents allow for fast and easy release of parts from molds without external spraying of a release agent. Specific end use requirements can also be met by redesigning the polyurea RIM system. Speed and physical properties of the polyurea RIM systems allow for creative designing in automotive applications. Polyurea RIM elastomers are making significant contributions in automotive fascia material.
