Duratron® CU60 PBI Polybenzimidazole

Duratron® CU60 PBI Polybenzimidazole is the highest performing engineering plastic available from Mitsubishi Chemical Group due to its superior mechanical properties, heat resistance, and mechanical property retention over 400°F / 205°C. It has better wear resistance and load carrying capabilities at extreme temperatures than any other reinforced or unreinforced advanced engineering plastic. This makes this material highly attractive to semiconductor manufacturers for vacuum chamber applications. In addition, Duratron® PBI is ideal for high heat bushings, connectors, valve seats, and probe tip lenses.
