Aromatic polyimide is a kind of super engineering plastics with excellent comprehensive properties (long-term service temperature is above 250 ℃), and it has excellent mechanical, thermal, dielectric, wear resistance and weather resistance characteristics, so it is called "problem-solving expert". Its outstanding comprehensive performance, widely used in aerospace, automotive, electronics and other fields. Most polyimides are insoluble or insoluble and difficult to process. As a kind of high-performance engineering plastics, thermoplastic polyimide gcpitm not only has excellent heat resistance, mechanical, dielectric, corrosion resistance and radiation resistance, but also shows excellent hot working characteristics. It can be molded by hot pressing, extrusion and injection molding. Gcpitm is compounded with carbon fiber, glass fiber, polytetrafluoroethylene and graphite, which can significantly improve the mechanical strength, self lubrication and wear resistance of the material.
