The full name of PEEK (PAEK) is polyether ether ketone (polyaryl ether ketone). It is a special engineering plastic with excellent performance. It has more advantages than other special engineering plastics. It is similar to polymethyl methacrylate and polycarbonate. Different from ester, nylon, etc., the polymer backbone of PEEK (PAEK) is mainly composed of benzene rings. This special structure makes it resistant to high temperatures, good mechanical properties, and chemical corrosion compared to other ordinary plastics. , radiation resistance, stable insulation and easy processing, etc., it is recognized as a thermoplastic material with high comprehensive performance in harsh environments.
