Peek rods, named in Chinese as polyetheretherketone rods, are a semi-finished shape formed by extrusion molding using peek raw materials, which have some characteristics such as high temperature resistance, high wear resistance, high tensile strength, and good fire retardant. Peek rods can be used to process peek parts of various specifications and can manufacture highly required mechanical components such as gear, bearings, valve holders, sealing rings, pump wear rings, washers, etc. Parts processed with PEEK rods are widely used in critical connections in areas such as aerospace, medical, semiconductor, pharmaceutical, and food processing industries.
