Shandong Junhao PEEK fine powder is a material obtained by grinding PEEK polymer coarse powder, which can be divided into low viscosity, standard viscosity and high viscosity (200-500 mesh). It can be used for molding, composite modification, prepreg and spraying. The 500 mesh fine powder is suitable for pure material spraying, and is widely used in chemical barrels, tanks, reaction kettles, stirring rods, alkali container heat exchangers, electroplating racks, acid-resistant and corrosion-resistant smoke exhaust pipes and other high temperatures. Improve the wear resistance, high and low temperature resistance, corrosion resistance of pipelines, reduce the inner wall wear of pipelines, avoid leakage, avoid falling off, have a long service life, and reduce the use cost, etc., and adopt advanced process equipment to develop and produce PEEK special materials for various application industries according to the needs of customers.
