A new thermoset polyester bulk molding compound from IDI Composites International, Noblesville, Ind., is designed for injection molding standard and high-intensity discharge (HID) automotive headlamps. BMC Grade A103 is said to provide superior dimensional stability during long-term exposure to heat and vibration, as well as exceptionally low emissions under high heat. Low emissions are essential for vacuum-metalized reflectors because volatiles can cause blistering. The new BMC also reportedly will not degrade under heat generated by HID lamps.
