PEEK exhibits very superior comprehensive properties 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 for its excellent electrical properties, mechanical properties, high temperature resistance, corrosion resistance, etc. PEEk5601G—high-purity PEEK particles are a higher purity grade of particles, belonging to the grade of particles with medium fluidity, which can be used for injection molding, extrusion production and processing. Its purity is higher than PEEK5600G, and it is suitable for higher requirements such as analytical instrument parts.
