PEEK application
Polyether ether ketone (PEEK) resin is a special engineering plastic with excellent performance, which has many significant advantages compared to other special engineering plastics,
High temperature resistance, excellent mechanical properties, good self-lubrication, chemical corrosion resistance, flame retardancy, peel resistance, radiation resistance, stable insulation
It is resistant to hydrolysis and easy to process, and has been applied in fields such as aerospace, automotive manufacturing, electronics and electrical, medical and food processing.
PEEK resin with excellent performance and wide application was first applied in the aerospace field, replacing aluminum and other metal materials to manufacture various aircraft components [4]. In the automotive industry, due to its excellent friction resistance and mechanical properties, PEEK resin is widely used as a raw material for manufacturing engine casings, and various components such as bearings, gaskets, seals, clutch gear rings, etc. are widely used in automotive transmission, braking, and air conditioning systems. PEEK resin is an ideal electrical insulator that can 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 pipelines, valves, and pumps for transporting ultra-pure water. In the semiconductor industry, it is commonly used to manufacture wafer carriers, electronic insulation membranes, and various connecting devices. As a semi crystalline engineering plastic, PEEK is insoluble in almost all solvents except concentrated sulfuric acid, and 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 suitable for producing surgical and dental equipment with high sterilization requirements and repeated use. PEEK molding temperature 320 ° C~390 ° C, drying temperature 160~1855H~8H, mold temperature 140~180. This material has a high molding temperature and causes serious damage to the screw. When setting the screw speed, the speed should not be too fast. The injection pressure should be between 100~130MPa and the injection speed should be between 40~80. After the molding is completed, the screw should be quickly cleaned with PE wax in a timely manner, and the PEEK material should not stay in the screw.
