Relying on its previous experience in the PEEK industry, Junhua Medical 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 customer R&D, production and feedback on profiles and parts, it will also promote the improvement of Junhao’s raw material resin polymerization. As an advanced engineering plastic, PEEK has good machinability, flame retardancy, non-toxicity, wear resistance, corrosion resistance and other properties. It plays an important role in weight reduction, effectively extending the service life of components, and optimizing component utilization. It plays an important role. With the acceleration of downstream application promotion, it is expected that the demand for PEEK in China will further grow in the future and be used in more fields.
PEEK exhibits very superior comprehensive properties because it contains a large number of benzene ring structures in its molecule.
PEEK (polyether ether ketone) resin is a high-performance special thermoplastic material and one of the important varieties of commercial polyaryl ether ketone resins. At present, polyetheretherketone is widely used in petroleum, food processing, automobiles, aerospace and other fields due to its excellent electrical properties, mechanical properties, high temperature resistance, corrosion resistance, etc.
PEEK powder is ground from the coarse powder after PEEK polymerization. According to different grinding processes, powders of different sizes from 200 mesh to 800 mesh can be ground.
