PEEK resin was first used in the aerospace industry to replace aluminum and other metal materials to manufacture a variety of aircraft components. In the automotive industry, PEEK resin has good friction resistance and mechanical properties. As a raw material for the manufacture of engine inner cover, various components such as bearings, gaskets, seals and clutch ring gears are used in the transmission and braking of automobiles. And widely used in air conditioning systems.
PEEK resin is an ideal electrical insulator. It can 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 used in the semiconductor industry to fabricate wafer carriers, electronically insulating diaphragms, and
Various connection devices. As a semi-crystalline engineering plastic, PEEK is insoluble in almost all solvents except concentrated sulfuric acid, so it is commonly used to make compressor valves, piston rings, seals and various chemical pump bodies and valve parts.
PEEK resin can also be subjected to up to 3000 cycles of autoclaving at 134 ¡ã C, a feature that makes it suitable for the production of surgical and dental equipment requiring high sterilization and re-use. PEEK not only has the advantages of light weight, non-toxicity and corrosion resistance, but also the material closest to human bones, which can be organically combined with the body. Therefore, using PEEK resin instead of metal to make human bones is another important application in the medical field. Domestic production and development 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 military material, and many countries have restricted exports.
