3,3',4,4'-Biphenyltetracarboxylic acid

Product Specification

3,3',4,4'-Biphenyltetracarboxylic acid

Chemical Description:
3,3',4,4' -biphenyl tetracarboxylic acid is converted to 3,3',4,4' -biphenyl dianhydride after dehydration, which can be polymerized with a variety of diamines to obtain polyimide insulation materials with excellent heat resistance, hydrolysis resistance, mechanical and flexible properties. Polyimide synthesized by bichemicalbook phthalic-anhydride and p-phenylenediamin has good temperature resistance, and the thermal decomposition temperature can reach more than 600ºC, which is one of the varieties with high thermal stability so far. At such a temperature, the original physical properties can be basically maintained in a short time.

Uses:
3,3',4,4' -biphenyl tetracarboxylic acid is converted to 3,3',4,4' -biphenyl dianhydride after dehydration, which can be polymerized with a variety of diamines to obtain polyimide insulation materials with excellent heat resistance, hydrolysis resistance, mechanical and flexible properties. The material can be used for a long time below 333 ° C and will not be brittle at -269 ° C. The mechanical strength of the polyimide is high, and the tensile strength of the polyimide film can reach 400MPa, and the change is small with the increase of temperature. In addition, such materials generally have good radiation resistance, excellent dielectric properties, stable chemical properties, strong creep resistance, excellent friction properties and other characteristics, and have been widely used in aerospace, microelectronics and atomic energy and other high-tech fields.
