With the continuous research and development of domestic PEEK particles and PEEK products, more and more fields have begun to use PEEK products, so what special performance does PEEK products have so popular?
PEEK products have a light proportion and good self-lubrication. Due to its good processing properties, it can be filled with carbon fiber and molybdenum disulfide to further improve the lubricating properties and mechanical strength. In addition, due to the rapid progress of the research and development level of domestic PEEK products in recent years, it has slowly entered the medical field from the inherent military industry and petroleum fields. What are the advantages of specific use in these areas? The wide application space of PEEK engineering plastics involves aviation, machinery, electronics, chemicals, automobiles and other high-tech industrial fields, and can manufacture gears, bearings, piston rings, support rings, sealing rings (letters), valves, wear-resistant rings and other high-demand mechanical parts. (1) Aerospace field: PEEK can replace aluminum and other metal materials to manufacture various aircraft components, with excellent flame retardant performance, can be used to manufacture aircraft internal parts, reduce the degree of aircraft fire hazards, has been successfully tried for Shenzhou spacecraft series models, currently in Boeing passenger aircraft, Airbus has begun to use a large number of materials; (2) Electronic and electrical field: PEEK has excellent electrical properties and is an ideal electrical insulator. In the harsh working environment such as high temperature, high pressure, high humidity, etc., it can still maintain good electrical insulation. Therefore, the electronic and electrical industry has gradually become the second largest application field of PEEK. Especially in the semiconductor industry, PEEK is often used in the manufacture of insulating films, connectors, printed circuit boards, high-temperature insulating films, connectors, printed circuit boards, high-temperature connectors, etc. At present, Japan, Europe and the United States and other countries have used PEEK materials to produce their ultra-large integrated circuits; (3) Medical field: In addition to surgery, dental equipment and some precision medical equipment with high requirements for production and sterilization, which need to be reused, the important application of PEEK is to replace artificial bone made of metal. Artificial bone made of PEEK has the advantages of light weight, non-toxic, strong corrosion resistance, etc., and can also be organically combined with the body. Therefore, PEEK has been successfully applied in the medical field; (4) Energy power and nuclear industry: PEEK is resistant to high temperature, not easy to hydrolyze and radiation, so its wire and cable coil skeleton has been successfully used in nuclear power plants; (5) Machinery industry: PEEK is commonly used in the manufacture of compressor valves, piston rings, seals and various chemical pump bodies and valve parts. Using PEEK instead of stainless steel to make the impeller of the vortex pump can significantly reduce the degree of wear and noise level, and extend its service life; (6) Automotive industry: the use of PEEK good friction resistance and mechanical properties, can be used as engine cover, automotive bearings, gaskets, seals, clutch tooth ring and other components of metal stainless steel and titanium substitute, can also be used for automotive transmission, braking and air conditioning systems, at present Audi, Mercedes-Benz, Nissan, Chrysler, General Motors and other companies have begun to use a large number of materials.
