Polyetheretherketone (PEEK) is a semi-crystalline high-temperature thermoplastic. Due to its biocompatibility, excellent physical and electrical properties, chemical resistance and easy sterilization, it is increasingly used in high-performance medical tubing, aviation, machinery, High-tech industrial fields such as electronics, chemicals, and automobiles.
PEEK polyether ether ketone resin was first used 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. It is used as the raw material for manufacturing the inner cover of the engine. The bearings, gaskets, seals, clutch gear rings and other parts made by it are used in the transmission and brakes of automobiles. And air-conditioning systems are widely used.
PEEK polyether ether ketone 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. Pipes, valves, and pumps for transporting ultrapure water 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. The characteristics of PEEK are as follows:
1. Good high and low temperature resistance, allowing long-term use at a temperature of 260 degrees.
2. The peek material can resist corrosion and resist aging.
3. The peek material has high resistance to dissolution.
4. The peek material has the conditions of high temperature, high frequency and high voltage electrical properties.
5. Peek material has strong flexibility and rigidity.
6. The peek material is more wear-resistant and has strong anti-corrosion properties.
7. The raw materials are implanted and interventional. (With biocompatibility report).
PEEK polyether ether ketone 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 polyether ether ketone not only has the advantages of light weight, non-toxicity, corrosion resistance, etc., it is also the material closest to human bones at present, and can be organically combined with the body. Therefore, it is important to use PEEK polyether ether ketone resin to replace metal to make human bones. Another important application in the medical field. Fast development of domestic production 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.
