| The English name of pyromellitic dianhydride is Pyromellitic Dianhydride (abbreviated as PMDA, the same below), which is mainly used for synthesizing polyimides. Due to the excellent ultra-high heat resistance, acid and alkali resistance, excellent mechanical properties, electrical properties and dimensional stability of polyimides, it is widely applied in high-tech fields such as aviation, aerospace, microelectronics and atomic energy, where strict requirements are placed on material performance. | |||||||||
