Release time:2020-08-31浏览:3653

    Polyether ether ketone (PEEK) resin is a special engineering plastic with excellent performance. Compared with other special engineering plastics, it has many significant advantages, such as high temperature resistance, excellent mechanical properties, good self-lubricity, chemical resistance, flame retardancy, Peel resistance, radiation resistance, stable insulation, hydrolysis resistance and easy processing, etc., are widely used in aerospace, automobile manufacturing, electronic and electrical, medical and food processing fields.

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

     PEEK resin is an ideal electrical insulator. It 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, manufacturing and transporting ultrapure water The pipelines, valves and pumps 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 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 not only has the advantages of light weight, non-toxicity, corrosion resistance, etc., it is also the closest material to human bones and can be organically combined with the body. Therefore, using PEEK resin to replace metal to make human bones is another important application in the medical field. Rapid domestic production 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 and military material, and many countries have restricted exports.
