PEEK polyether ether ketone resin was first used in the aerospace industry to replace aluminum and other metal materials in a variety of aircraft parts. Due to its good friction resistance and mechanical properties, PEEK resin is widely used in automobile transmission, brake and air conditioning systems as a raw material for the manufacture of engine housings. Bearings, gaskets, seals, clutch gear rings and other parts manufactured with PEEK resin are widely used in automobile transmission, brake and air conditioning systems.

PEEK polyether ether ketone resin is an ideal electrical insulator, which can maintain good electrical insulation performance under harsh working conditions such as high temperature, high pressure and high humidity. Therefore, the field of electronic information has gradually become the second largest application field of PEEK resin, including the manufacture of pipes, valves and pumps for conveying ultra-pure water. In the semiconductor industry, It is commonly used to manufacture wafer bearers, electronic insulating diaphragms and various connecting devices. As a semi-crystalline engineering plastic, PEEK polyether ether ketone is insoluble in almost all solvents other than concentrated sulfuric acid, so it is commonly used to make compressor valve plates, piston rings, seals and various chemical pump body, valve parts.

PEEK also withstands up to 3,000 cycles of autoclave at 134 ° C, which makes it suitable for the production of highly sterilized surgical and dental equipment that requires repeated use. PEEK polyether ether ketone not only has the advantages of light weight, non-toxic, corrosion resistance and so on, is the material closest to the human skeleton at present, can be organically-combined with the body, so PEEK polyether ether ketone resin instead of metal manufacturing human skeleton is another important application in the medical field. The rapid development of domestic production PEEK resin was developed by the former ICI Company in the late 1970s. Since it came out, PEEK resin has been used as an important strategic military industrial material for national defense, and many countries have restricted its export.
