Thermoplastic Polyimide Engineering Plastic
Polyimides (PIs) with cyclic imide structures in the backbone, play an important role in the family of high performance resins. However, the applications of PIs are rather limited due to their high cost. Using chlorophthalic anhydride isomers as starting materials and choosing either polythioetherimides or polyetherimides instead of UltemTM as major objects, we have developed a low-cost and injection-moldable PI engineering plastic which can be continuously used at up to 230 ºC. Today, the low-cost and melt-processable PI resins have been successfully prepared in our lab.
