Peek rod, Chinese name for peek rod, is a kind of semi-finished profile extruded with PEEK raw material, which has the characteristics of high temperature resistance, high wear resistance, high tensile strength and good flame retardancy. Peek rod can be used to process various specifications of PEEK parts, and can be used to manufacture mechanical parts with high requirements, such as gears, bearings, valve seats, sealing rings, pump wear rings, gaskets, etc. The parts processed with PEEK rods are widely used in key connectors in aerospace, medical, semiconductor, pharmaceutical and food processing industries.

The density of pure peek rod is about 1.35, and that of modified peek rod is about 1.42. However, it should be noted that the outer diameter of PEEK rod is generally larger than the calibrated one, so the weight of single peek rod should be based on the actual outer diameter. For example, the control sizes of 10 mm peek rods from different manufacturers are different, some of which are 10.5, 10.8 or even 11, resulting in different weights.

The general weight formula of PEEK rod is: mass = Volume X density.
