Premier PEI-140 lightweight, electrically conductive plastic is for EMI shielding of high-temperature avionics. Is said to maintain high-temperature tolerance, chemical resistance and UL 94V-0 flammability rating for a shielding solution up to 85dB in aerospace applications. Complies with avionics smoke density requirements. PolyEtherImide was chosen for its thermal resistance, mechanical properties, flame resistance and low smoke generation. Is an amorphous thermoplastic reinforced with matrix of proprietary conductive fillers. Continuous use at temperatures up to 340°F.
