PEEK support ring has good performance, stable size, and can be customized. PEEK support ring is featured with high temperature resistance, wear resistance, and strong mechanical properties. Introduction of PEEK material: the PEEK with high temperature resistance has a high glass transition temperature and melting point (334℃), which is one of the reasons that it can be used reliably in the use of heat resistance requirements. For the PEEK support ring, its load thermal variation temperature is as high as 316℃, continuous service temperature is 260℃. PEEK has excellent comprehensive performance which is incomparable to other general plastics in high-performance polymers and is suitable for various harsh environments. It has been successfully and widely used in aerospace, automobile, electronic semiconductor, electromechanical and other industries which are demanding occasions. It is the first choice material for users to develop new products and improve the service life and reliability of products.
