On September 11, China National Chemical Engineering Group and GDYJ Polymer Materials Technology Group held a signing ceremony for the special engineering plastic polyetherimide/PEI project. The project is EPC general contracted by China National Chemical Engineering Group Wuhuan Company.
The signing of the project by China National Chemical Engineering Group Wuhuan Company marked the entry into the implementation stage of China's high-end special engineering plastic polyetherimide project. After the project is completed, the product quality will reach the international leading level. The successful implementation of the project will break the monopoly of foreign technology on China's polyaromatic special engineering plastics, effectively fill China's technological gap in this field, and greatly ease the external dependence of China's domestic related industries on such materials.
Polyetherimide (PEI) is an amorphous high-performance polymer with the best high temperature resistance and dimensional stability, as well as chemical resistance, flame retardancy, electrical properties, high strength, and high rigidity. , Can be widely used in high temperature resistant terminals, IC base, lighting equipment, FPCB (flexible circuit board), liquid conveying equipment, aircraft internal parts, medical equipment and household appliances and other industries.
