PEEK resin was earlier applied 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 diaphragms 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.

PEEK resin can also withstand up to 3000 cycles of high-pressure sterilization at 134 ℃, which makes it applicable to the production of surgical and dental equipment with high sterilization requirements and requiring repeated use. PEEK not only has the advantages of light weight, non-toxic, corrosion resistance, but also is a material closer to human bones at present, which can be organically combined with the body. Therefore, it is another important application of PEEK resin in the medical field to replace metal to make human bones. PEEK resin with rapid development in domestic production was developed by the former British ICI Company in the late 1970s. Since its inception, PEEK resin has been used as an important strategic defense military material, and many countries have restricted its export.
