This new low-wear, high-abrasion resistant modified PEEK compound meets the demanding requirements for mechanical load-bearing and lubrication performance under harsh high-temperature and chemical environments. Compared with carbon-fiber-reinforced PEEK, it offers significantly improved wear resistance, a considerably lower coefficient of friction, and better dimensional stability. Under equivalent load conditions, wear loss is greatly reduced, thereby enhancing product durability. 1.Low coefficient of friction: 0.1699. 2.Low wear rate. 3.Low coefficient of thermal expansion: 3×10−6.
