PEEK exhibits very superior comprehensive performance because of the large number of benzene ring structures in its molecules. PEEK (polyetheretherketone) resin is a high-performance special thermoplastic material and one of the important varieties of commercial polyaryletherketone resins. At present, polyetheretherketone is widely used in petroleum, food processing, automobile, aerospace and other fields with its excellent electrical properties, mechanical properties, high temperature resistance, corrosion resistance, etc. PEEk5600G is a grade particle with a medium melt flow rate, which can be used for production and processing by injection molding and extrusion. Its purity can reach more than 99%. Relying on the previous experience accumulated in the PEEK industry, the company has entered the polymerization production of PEEK resin, providing more choices and stronger guarantees for domestic PEEK parts and profiles, and creating advantageous conditions for the development of domestic PEEK. At the same time, through the research and development, production and feedback of customers on profiles and parts, it will also promote the improvement of Junhao’s raw material resin polymerization.
