The GHS information provided by 1 company from 1 notification to the ECHA C&L Inventory.
使用3,3',4,4'-Biphenyltetracarboxylic acid is converted to 3,3',4,4'-biphenyl dianhydride after dehydration, and the latter can be polymerised with a variety of diamines to obtain polyimide insulating materials with excellent heat resistance, hydrolysis resistance, and good mechanical and flexibility properties. This material has been widely used in aerospace, microelectronics and atomic energy and other high-tech fields.
