Material Notes:
PEI-140 can provide up to a 65% cost reduction by eliminating secondary operations such as assembly, machining, painting/plating and the logistics that accompany these processes. The shielding effectiveness, high temperature performance, low smoke generation, chemical resistance and UL 94V-0 flammability rating combined with a weight savings of 50-75%, make using PEI-140 for aerospace applications economically viable. PEI-140 specific gravity is 40% less than aluminum and 80% less than steel. PEI-140 offers an opportunity to reduce the weight of airborne electronic housings by up to 75%. PEI-140 housings will not only cost less themselves, but also improve aircraft operating cost through weight reduction.Information provided by Chomerics
