High temperature resistance, excellent mechanical properties, good self lubrication, chemical corrosion resistance, flame retardant, peeling resistance, radiation resistance, stable insulation
It is resistant to hydrolysis and easy to process, and has been applied in the fields of aerospace, automobile manufacturing, electronics and electrical, medical treatment and food processing.
Excellent performance and wide application peek resin was first applied in the aerospace field to replace aluminum and other metal materials to manufacture various aircraft parts. In the automotive industry, peek resin has good friction resistance and mechanical properties. As a raw material for manufacturing engine hood, it is used to manufacture bearings, gaskets, seals Clutch gear ring and other parts 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. It is used to manufacture pipelines, valves and pumps for transporting ultrapure water. In the semiconductor industry, it is commonly used to manufacture wafer carriers Electronic insulating diaphragm 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 plate, piston ring, seal 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 the production of surgical and dental equipment with high sterilization requirements and repeated use. Peek molding temperature is 320 ℃ ~ 390 ℃, drying temperature is 160 ~ 1855h ~ 8h, mold temperature is 140 ~ 180. The molding temperature of this material is too high, which causes serious damage to the screw. The speed cannot be too fast when setting the screw speed. The injection pressure is 100 ~ 130Mpa, and the injection speed is 40 ~ 80. After molding, the screw shall be quickly cleaned with PE wax in time, and peek materials shall not stay in the screw.
