| Description: | roduct Deion ODPA is a kind of important monomer for synthesizing polyimide, because in ODPA, there includes the ether base flexible base group. The polyimide(PEI) that synthesized by taking the ODPA as the monomer can increase the entire molecular chain''s flexibility, also can improve the polymer''s solubility and extensibility, thus reduce the intermolecular force and the vitrification temperature, its workability can have remarkable improvement and a more outstanding performance. In the application aspect of the electric insulation material, in the electricity minimum, the high-capacity and the heat-resisting enhancement and so on aspects, it has already become the inestimable important material; And at the production aspect of the high-temperature unlubricating oil bearing, it also has extremely high use value. Moreover in recent years, because of the fast development of the astronavigation, missile, electron, electromechanical, traffic transport industry and so on industries, we urgently need a new-type high molecular material which can maintain the engineering structure intensity under highly changed temperature difference and under the conditions of large dose penetrating radiation and corrosive medium function, as well as the burning condition, etc, undoubtedly, the PEI is one of the ideal materials which conforms to the above requests. Its enhancement level, modification level, copolymerization level, foam plastics, mould pressing product, textile fiber, coating, binder and the enamelled wire and so on, all can be used as the precise components that work under special conditions. The limiting temperature resisting performance is extremely superior. | |
