CA 2141884

The present invention relates to a process for the preparation of a SRIM molded product wherein the mold cavity has minimum dimensions of 1000mm × 100mm × 3.5 mm. The reaction mixture comprises an isocyanate component and an isocyanate reactive component at an isocyanate index of from about 90 to about 400. The reinforcing fiber mat comprises from 50 to 65% by weight, based on the combined weight of the reaction mixture and the reinforcing fiber mat. In particular, the isocyanate component is 1) a polymethylene poly(phenyl isocyanate) having an isocyanate group content of from 25 to 40% by weight, and a diisocyanate content of 45-55% by weight; and 2) the isocyanate-reactive component comprises a) from about 1 to 15% by weight, based on the total weight of said isocyanate reactive component, of a fatty acid.
