Polyether ether ketone (PEEK) resin is a kind of special engineering plastics with excellent performance. Compared with other special engineering plastics, it has many significant advantages, such as high temperature resistance, excellent mechanical properties, good self-lubricating property, chemical corrosion resistance, flame retardancy, peel resistance, radiation resistance, stable insulation, hydrolysis resistance and easy processing. It is widely used in aerospace, automotive manufacturing, electronics and electrical, medical and food processing fields.　　

Excellent performance and wide application PEEK resin was applied earlier in the aerospace field, replacing aluminum and other metal materials to manufacture various aircraft parts. In the automotive industry, because PEEK resin has good friction resistance and mechanical properties, as the raw material for manufacturing the engine inner cover, various components such as bearings, gaskets, seals, clutch gear rings, etc. manufactured with PEEK resin are widely used in automotive transmission, braking and air conditioning systems.

PEEK resin is an ideal electrical insulator, which can still maintain good electrical insulation performance under harsh working conditions such as high temperature, high pressure and high humidity. Therefore, the electronic information field has gradually become the second largest application field of PEEK resin, which manufactures pipes, valves and pumps for transporting ultra pure water. In the semiconductor industry, it is commonly used to manufacture wafer carriers, electronic insulation membranes and various connecting devices. As a semi crystalline engineering plastic, PEEK is insoluble in almost all solvents except concentrated sulfuric acid, so it is often used to make compressor valve plates, piston rings, seals and various chemical pump bodies and valve components.
