A new bulk molding compound is said to have four times the impact strength and triple the tensile strength of standard BMC. Super-Tough BMC from Bulk Molding Compounds Inc., West Chicago, Ill., boasts notched Izod impact of 29 ft-lb/in., tensile strength of 16,000 psi, and flexural strength of 30,000 psi. It combines polyester, epoxy, and a TPE plus 35% reinforcement (glass and a proprietary thermoplastic fiber). It is designed to replace metal in automotive oil drain pans, valve covers, and door modules, as well as electric motor housings. It reportedly passes the demanding automotive gravelometer test, which subjects a part to air-blown gravel at high temperature.
