China has become the world's most important producer of polyimide raw materials, and the raw materials for PMDA and ODA products have been recognized by many international manufacturers.
Polyimide is mainly synthesized by dianhydride and diamine.Compared to other heterocyclic polymers such as polybenzimidazole, polybenzimidazole, polybenzothiazole, polyquinoline and polyquinoline, these monomers have the advantage of a comprehensive source of raw materials and ease of synthesis. There are many varieties of dianhydride and diamine. Different combinations can obtain different properties of polyimide. At present, there is a mature supply chain for ODA and PMDA in China.
Recently, fluorinated polyimide is becoming more and more popular in the field of optoelectronics. Since 2008, we have supplied various raw materials for PI films to more than 10 customers, including famous manufacturers such as Du** and S*.
