Polyurea RIM polymers have been developed for automotive fascia and body panels ranging in flexural modulus from 25K to 120K. These materials characteristically have thermal and impact properties that are superior to polyurethanes or polyurea/polyurethanes. The polyurea polymers do not require post cure, yet yield thermal properties that are better than polyurethanes containing as much as 20% reinforcing fillers.A variety of self-releasing, polyurea RIM systems have been developed based on advances in isocyanate prepolymer technology. These systems, while varying in flexural modulus from 25K to 100K, employ a resin system having a constant equivalent weight.
