Industrial Dielectrics Inc. said its IDI Composites International unit developed a new bulk molding compound formulated for automotive use.
BMC Grade A103 provides long-term dimensional stability and very low emissions under high temperatures. The thermoset resin also resists corrosion and creep, and has a very high strength-to-weight ratio.
Those properties make Grade A103 well-suited for headlamp reflectors, which are created in a vacuum metalization process. The polyester-based BMC outperforms thermoplastics in that application, according to Noblesville, Ind.-based IDI Composites.
