Mechanical industry. Because PEEK has high temperature resistance, corrosion resistance, fatigue resistance, friction resistance characteristics, many international and domestic equipment parts, such as bearings, piston rings, reciprocating gas compressor valve plate, etc. widely used PEEK.
Energy and chemical resistance to high temperatures, high humidity, radiation and other excellent performance in the nuclear power plant and other energy industry, chemical field has been widely used.
Applications in the electronic information industry In the international arena this is the second largest application of PEEK, the amount of about 25%, especially in the transmission of ultrapure water, the application of PEEK made of piping, valves, pumps, in order to make ultrapure water is not contaminated, has been widely used abroad.
Aerospace industry. As a result of PEEK's superior overall performance, since the 1990s, foreign countries have been widely used in aerospace products, domestic products in the J8-II aircraft and the Shenzhou spacecraft products on the successful trial.
Automotive industry. Energy saving, weight reduction, low noise has been the development of automotive requirements of the important indicators, PEEK lightweight, high mechanical strength, heat resistance, self-lubricating properties to meet the needs of the automotive industry.
Medical and health fields. PEEK in addition to the production of a number of precision medical instruments, the most important application is to replace the metal production of artificial bone, lightweight, non-toxic, corrosion-resistant and other advantages, can also be organically combined with the muscle, is the closest material with the human bone.
PEEK in the aerospace, medical, semiconductor, pharmaceutical and food processing industries have been very common applications, such as satellite gas partition instrument components, heat exchangers scraper; because of its superior friction properties, in the friction application areas become ideal materials, such as sleeve bearings, plain bearings, valve seats, seals, pumps, wear-resistant rings. Various parts for production lines, parts for semiconductor liquid crystal manufacturing equipment, and parts for inspection equipment.
