Duratron CU60 PBI
2Pages

MITSUBISHI CHEMICAL GROUP PRODUCT DATASHEET 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.

Notes, see datasheet on page 1 1. The figures given for these properties are for the most part derived from raw material supplier data and other publications. 2. Values for this property are only given here for amorphous materials and for materials that do not show a melting temperature (PBI & PI). 3. Temperature resistance over a period of min. 20,000 hours. After this period of time, there is a decrease in tensile strength – measured at 23 °C – of about 50 % as compared with the original value. The temperature value given here is thus based on the thermal-oxidative degradation which takes...
