Polyimide (PI) has excellent resistance to high temperature, low temperature, solvent, radiation, and outstanding mechanical strength and dielectric properties. It has been widely used in many high-tech fields such as aerospace, aviation, automobiles, electronic semiconductors, welding and cutting, and electrical appliances. However, the difficulty in processing and high manufacturing costs of polyimide (PI) have always been two key factors restricting its rapid development. Research and development of melt-processable thermoplastic polyimide (PI) is one of the main methods to enable it to have processing and molding properties and reduce manufacturing costs. Thermoplastic polyimide (PI) not only retains the characteristics of traditional thermosetting PI, but also improves processability. In addition to hot compression molding, it can also be molded by extrusion or injection.

Since thermoplastic PI has poor thermal stability, is easy to degrade and hydrolyze, and is accompanied by serious die swelling effect and other problems, it directly affects the production of continuous extrusion of thermoplastic polyimide (PI), resulting in almost no domestic manufacturers being able to achieve continuous extrusion molding of polyimide (PI) profiles.

After a long period of exploration, Jiangsu Junhua Special Engineering Plastic Products Co., Ltd. has been able to maturely and stably extrude thermoplastic polyimide (PI) profiles continuously. Customers are welcomes customers to inquire..
