The growth of PEEK resin in the European market, especially in the auto parts market, is the fastest, especially in the parts around the engine, transmission parts, steering parts, etc., which use PEEK plastics instead of some traditional high-priced metals as manufacturing materials. Demand for PEEK resins will continue to grow as the automotive industry adapts to miniaturization, lightweighting and cost reduction. A European model has 44 parts that use PEEK plastic instead of traditional metal products.

2. The field of IT manufacturing

Semiconductor manufacturing and the electrical and electronic industry are expected to be another growth point for PEEK resin applications.

Polyetheretherketone (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-lubrication, chemical corrosion resistance, flame retardant, Peeling resistance, radiation resistance, stable insulation, hydrolysis resistance and easy processing, etc., have been used in aerospace, automobile manufacturing, electrical and electronic, medical and food processing and other fields.

Excellent performance and wide application PEEK resin was first used in the aerospace field, replacing aluminum and other metal materials to manufacture various aircraft parts [4] In the automotive industry, because PEEK resin has good friction resistance and mechanical properties, it is used in the manufacture of engine inner covers. Various components such as bearings, gaskets, seals, clutch gear rings, etc. made of it are widely used in automobile transmission, braking and air conditioning systems. 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 field of electronic information has gradually become the second largest application field of PEEK resin, manufacturing and transporting ultrapure water. In the semiconductor industry, it is often used to manufacture wafer carriers, electronic insulating 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 parts. PEEK resins can also withstand up to 3000 cycles of autoclaving at 134°C, a feature that makes them useful in the production of sterilization-critical, reusable surgical and dental equipment. The molding temperature of PEEK is 320 degrees ~ 390 degrees, the baking temperature is 160~1855H~8H, and the mold temperature is 140~180. The molding temperature of this material is too high, and the damage to the screw is serious. When setting the screw speed, the speed should not be too fast, and the injection pressure should be 100 ~130MPa injection speed 40~80. After molding, the screw should be quickly cleaned with PE wax, and the PEEK material should not be allowed to stay in the screw.
