• The polyimide powder refers to a type of polymer having an imide ring (-CO-N-CO-) in its main chain, and a polymer containing a phthalimide structure is most important. As a special engineering material, polyimide has been widely used in aviation, aerospace, microelectronics, nano, liquid crystal, separation membrane, laser and other fields. In the 1960s, countries were including the research, development and utilization of polyimides as one of the most promising engineering plastics of the 21st century.
