Abstract
A thermally-conductive polymer composition suitable for making molded reflector articles having light-reflecting surfaces is provided. The composition comprises: a) about 20% to about 80% by weight of a base polymer matrix such as polycarbonate; and b) about 20% to about 80% by weight of a thermally-conductive carbon material such as graphite. The composition can be used to make reflector articles such as housings for automotive tail lamps, head lamps, and other lighting fixtures. A method for manufacturing reflector articles is also provided.
Claims7
