Gain knowledge! PEEK Polyether Ether Ketone Product Introduction
Polyether ether ketone (PEEK), also known as polyetheretherketone in Chinese. PEEK is a partially crystalline material with a glass transition temperature of 143 ℃ and a melting temperature of 334 ℃. The material is resistant to organic and water environments and is widely used in bearings, pistons, water pumps, compressor valve plates, cable insulation, etc.
PEEK is a high-performance specialty engineering plastic developed by Imperial Chemical Industries (ICI) in 1978. Similar products have also been developed by companies such as DuPont, BASF, Mitsui Toho Chemicals, VICTREX, and Caltex in the United States. Among them, ICI's PEEK has been transferred to VICTREX for production. In China, due to its excellent performance, PEEK is regarded as a strategic defense and military material, and its research has been included in the national key scientific and technological research projects and the "863 Program" from the Seventh Five Year Plan to the Fifteenth Five Year Plan. The main production and research manufacturers include Suwei from the United States and Da Ying Chuang High Performance Polymer Company. Dongguan PRES focuses on the production, research and development, and sales of PEEK materials.
This material has excellent chemical resistance, thermal stability, and oxidation resistance, as well as good mechanical strength, creep resistance, and electrical properties. It can withstand high-energy radiation and has good flame retardant properties. The long-term working temperature range of PEEK can be from -100 ℃ to+250 ℃.
Excellent chemical resistance
● High temperature and low temperature resistance
● Not easily worn and wear-resistant
Continuous exposure to hot water or steam is not affected
PRES Polyether Ether Ketone (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-lubricating properties, chemical corrosion resistance, flame retardancy, peel resistance, radiation resistance, insulation stability, hydrolysis resistance, and easy processing. It has been widely used in aerospace, automotive manufacturing, electronic and electrical, medical, and food processing fields.
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. Due to the excellent friction resistance and mechanical properties of PEEK resin in the automotive industry, it is widely used as a raw material for manufacturing engine covers. Various components such as bearings, gaskets, seals, clutch rings, etc. made from PEEK resin are widely used in the transmission, braking, and air conditioning systems of automobiles.
PEEK polyetheretherketone 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 area of PEEK resin, manufacturing pipelines, valves, and pumps for transporting ultrapure 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 therefore commonly 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 not only has the advantages of light weight, non toxicity, and corrosion resistance, but also is currently the closest material to human bones, which can be organically combined with the body. Therefore, using PEEK resin instead of metal to manufacture human bones is another important application in the medical field. The rapid development of domestic production of PEEK resin was developed by the former British ICI company in the late 1970s. Since its inception, it has been regarded as an important strategic defense and military material, and many countries have restricted its export.
Regarding PRES:
PRES is a company that mainly produces special engineering plastics such as PEEK polyetheretherketone, PPS polyphenylene sulfide, PEI polyetherimide, PPSU polyphenylsulfone, and is also one of the largest producers in Guangdong Province. Products such as PEEK particles, plates, and bar profiles are mainly used in special high-end application fields such as electronic applications, high-performance aviation, automotive parts, and petrochemicals.
