PEEK polyether ether ketone resin was first used in the aerospace field, replacing aluminum and other metal materials to manufacture various aircraft parts. In the automotive industry, PEEK resin has good friction resistance and mechanical properties. As a raw material for the manufacture of engine inner covers, various components such as bearings, gaskets, seals, clutch gear rings, etc. are used in the transmission and brakes of automobiles. And air-conditioning systems are widely used.

PEEK polyether ether ketone resin is an ideal electrical insulator. It can still maintain good electrical insulation performance under severe 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. Pipes, valves, and pumps for transporting ultrapure water are commonly used in the semiconductor industry to manufacture wafer carriers, electronic insulating films, 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 valves, piston rings, seals, and various chemical pump bodies and valve parts.

PEEK polyether ether ketone resin can also withstand up to 3000 cycles of autoclaving at 134°C. This feature makes it suitable for the production of surgical and dental equipment with high sterilization requirements and repeated use. PEEK polyether ether ketone not only has the advantages of light weight, non-toxicity, corrosion resistance, etc., it is also the material closest to human bones at present, and can be organically combined with the body. Therefore, it is important to use PEEK polyether ether ketone resin to replace metal to make human bone Another important application in the medical field. Fast development of domestic production PEEK resin was developed by the former British ICI company in the late 1970s. Since its inception, it has been used as an important strategic defense and military material, and many countries have restricted exports.
