Description of imported peek rod:
Peek is a high temperature resistant and high performance thermoplastic special engineering plastic. It has good mechanical properties, chemical resistance, wear resistance and hydrolysis resistance; It has light specific gravity and good self-lubricating performance. Due to its very good processing performance, it can be filled with carbon fiber and molybdenum disulfide to further improve the lubricating performance and mechanical strength. Peek engineering plastics has broad application space, involving aviation, machinery, electronics, chemical industry, automobile and other high-tech industrial fields. It can manufacture high-demand mechanical parts, such as gear, bearing, piston ring, support ring, sealing ring (letter), valve plate, wear ring, etc. The excellent performance of PEEK materials is mainly reflected in the following aspects:
High temperature resistance
Peek has a high glass transition temperature and melting point (334 ℃), which is one of the reasons why it can be reliably used in applications with heat resistance requirements. The load thermal deformation temperature is up to 316 ℃, and the continuous service temperature is 260 ℃.
Peek is a plastic with both toughness and rigidity. In particular, its excellent fatigue resistance to alternating stress is outstanding among all plastics and comparable to alloy materials.
Peek has outstanding sliding characteristics in all plastics and is suitable for applications with strict requirements for low coefficient of friction and friction resistance. In particular, the self-lubricating performance of PEEK modified by carbon fiber and graphite is better.
Chemical resistance (corrosion resistance)
Peek has excellent chemical resistance. In common chemicals, only concentrated sulfuric acid can dissolve or destroy it, and its corrosion resistance is similar to that of nickel steel.
Peek is a very stable polymer. A 1.45MM thick sample can reach a high flame retardant standard without any flame retardant.
Peek has good peel resistance, so it can be made into thin coated wires or electromagnetic wires, and can be used under harsh conditions.
Peek has good fatigue resistance in all resins.
Endure γ The irradiation ability is very strong, which exceeds that of polystyrene with good irradiation resistance in general resin. Can be made γ It is a high-performance wire that can maintain good insulation when the irradiation dose reaches 1100mrad.
Peek and its composites are not affected by the chemical effects of water and high-pressure water vapor. The products made of this material can still maintain excellent properties when used continuously in high-temperature and high-pressure water.
Application of mechanical industry
Because peek has the characteristics of high temperature resistance, corrosion resistance, fatigue resistance and friction resistance, peek is widely used in many equipment parts at home and abroad, such as bearings, piston rings and valve plates of reciprocating gas compressors.
Energy and chemical applications
It has excellent properties such as high temperature resistance, high humidity resistance and radiation resistance. It has been widely used in energy industry and chemical industry such as nuclear power plant.
3. The application of electronic information industry in the world is the second largest application field of PEEK, with a consumption of about 25%, especially in the transportation of ultrapure water. Only by using the pipes, valves and pumps made by peek can the ultrapure water not be polluted, which has been widely used abroad.
Aerospace Industrial Applications
Due to the superior comprehensive performance of PEEK, it has been widely used in aerospace products abroad since the 1990s, and has been successfully tried on the products of j-8-ii aircraft and Shenzhou spacecraft at home.
Automotive industry applications
Energy saving, weight reduction and low noise have always been important indicators required by automobile development. Peek’s characteristics such as light weight, high mechanical strength, heat resistance and self lubrication just meet the needs of the automobile industry.
Application in medical and health field
In addition to making some precision medical instruments, peek’s most important application is that it can replace metal producers to make bone. It has the advantages of light weight, non-toxic and strong corrosion resistance. In addition, peek can also be organically combined with the body. It is a material close to human bone.
Peek is widely used in aerospace, medical, semiconductor, pharmaceutical and food processing industries, such as gas plate splitter components and heat exchanger blades on satellites; Because of its superior friction performance, it has become an ideal material in the field of friction applications, such as sleeve bearing, sliding bearing, valve seat, sealing ring, pump wear ring and so on.
