In recent years, the polyimide resin AURUM® has been attracting increasing attention due to its outstanding properties. Its application range is expanding into a variety of areas, going beyond the boundaries of the electronics industry. AURUM® is an entirely new type of thermoplastic polyimide resin developed by Mitsui Chemicals on its own, making full use of its technology. The expansion of the application range of AURUM® has been made possible because of its thermoplasticity, which is suitable for injection molding and extrusion, as well as its unparalleled high heat resistance and mechanical and electrical properties.
