PRC is the only commercial producer of composite sheet molding compound on the west coast of the United States. ​ Our Thermoset Polyester based compounds contain 20% - 50% discontinuous glass fiber, custom colors, fillers and process aids to deliver excellent molding results. ​ Our compounds deliver high strength and impact resistance to the molded composite parts. The discontinuous nature of the fiberglass reinforcement allows these materials to be molded into complex geometries by compression molding.

PRCC engages with customers to develop custom compounds for compression molding applications. Our team has the capability to vary all key ingredients such as resin type, fiberglass content, exclusive colors, filler type and content, and process aids to maximize performance of the compound utilized for compression molding. Compounds can be delivered domestically in gaylords or returnable containers.​ The materials can be tested for mechanical properties and also sample molded on site prior to commercialization.​ Our team works with companies to assure a smooth transition of our compounds and optimizing molding parameters to deliver the highest quality compression molded composite components.
