PEEK high performance prospects
Polyether ether ketone (PEEK) resin is a high performance engineering plastics, and other specialty engineering plastics has many significant advantages, high temperature, excellent mechanical properties, good self-lubrication, corrosion resistance, chemical resistance, flame retardant, peeling resistance, radiation resistance, insulation and stability, water resistance and easy processing, etc., in the aerospace, automotive, electrical and electronics, medical and food processing and other fields are widely used.
Wide application performance PEEK resin to obtain the earliest applications in the aerospace field, instead of aluminum and other metal materials manufacture of various aircraft parts. PEEK resin as the automotive industry has good abrasion resistance and mechanical properties, as a raw material manufacturing the engine cover, with its manufacture bearings, gaskets, seals, clutch teeth rings and other parts of the car transmission, brakes and air conditioning systems are widely used.
PEEK resin is ideal for electrical insulation, high temperature, high pressure and high humidity, poor working conditions, can still maintain good electrical insulation properties, so the field of electronic information has become the second largest application areas PEEK resin, manufacture ultrapure water transport pipes, valves and pumps, in the semiconductor industry, used to manufacture the wafer carrier, electronic insulating film and a variety of connected devices. As a semi-crystalline engineering plastics, PEEK insoluble in concentrated sulfuric acid in almost all solvents, and thus used to produce compressor valves, piston rings, seals, and a variety of chemical pump, valve member.
PEEK resin at 134 ℃ can withstand up to 3000 times lower autoclave cycle, this feature so that it can be used to produce sterile demanding, require repeated use of surgical and dental equipment. PEEK is not only lightweight, non-toxic, corrosion resistance, etc., or is currently working with the closest human skeletal material that can combine with the body, so with PEEK resin instead of metal human skeleton in the medical field is another important application. Rapid development of domestic production of PEEK resin is 20 in the late 1970s by the British former ICI developed, since its inception, has been used as an important strategic national defense materials, many countries restrict exports.
During this period, our country only a few research institutions in the process of strict import application procedures only after a small amount of imports. With the PEEK resin in the automotive, electronics, machinery and other civilian areas of extensive application began to relax its export restrictions. Research and development of PEEK resin begins "Plan" period, is included in the national key scientific and technological projects and the "863" project consists of Jilin University commitment. After nearly 20 years of work, Jilin University, special engineering research center developed with independent intellectual property rights of PEEK resin synthesis route, the resin main performance reached the level of similar foreign products, and raw materials and equipment, all based on domestic resources, reduce production costs. Chittagong by the Changchun High-tech Materials Co., Ltd. invested 100 million yuan construction of 500 tons / year industrial unit by the end of 2002 a project was put into operation 300 tons, two will also be put into operation in October this year.
In the international market, PEEK resin price is too high is the key to limiting its application, and made the first breakthrough in the PEEK resin that. Since the 1990s, the domestic petrochemical industry imported over 2000 reciprocating gas compressors, these compressors are imported PEEK resin valves, PEEK resin production in the domestic front, only the petrochemical industry each year will cost 50 million yuan on for the replacement of this valve. PEEK resin-made mass production, Wenzhou, two metal valve manufacturer with high-tech materials Chittagong limited liability companies, the use of domestic resin successful trial PEEK valve plate, its performance considerably with imported products, and sells for less than the inlet valve plate half. Domestic PEEK valve plate with price advantage, quickly occupied the domestic market often has successfully developed a series of past domestic to rely on imports of PEEK resin products.
Currently, nearly 40 customers began using domestic PEEK resin trial related products. Mass production of PEEK resin PEEK resin products to promote the domestic development of the industry. To further meet the manufacture of high precision, heat-resistant, wear-resistant, anti-fatigue and impact parts at the request of PEEK for blending, filling, fiber reinforced composites such modification, you can get more excellent performance PEEK composites.
PEEK blend obtained polyether having a specific melting point and glass transition temperature of a particular composite material, the molding performance is improved; PEEK composite by blending polyether materials having good mechanical properties at the same time, the flame retardant Performance has been improved; PEEK added in phenolic resin made of special materials with a special anti-friction properties; PEEK and PTFE blends made of composite material, of PEEK in maintaining high strength, high hardness at the same time, also has outstanding abrasion resistance, can be used to manufacture bearings, seal rings and other mechanical components; carbon fiber and glass fiber and other fiber reinforced modified, can be made of high performance composite materials, fiber reinforced PEEK composite material , with excellent creep resistance, heat resistance, aging and impact resistance, but also greatly improve the tensile and flexural strength; whisker added in PEEK, can improve the hardness, rigidity and dimensional stability , for the manufacture of large-scale petrochemical production line hydrogen compressor and liquefied petroleum gas compressor ring, mesh valve tablets.
Inorganic nanomaterials reinforced modified PEEK composites, is a high-performance organic resin and inorganic nanoparticles many features in a new composite material. Reinforced modified PEEK broader technology paves the way for the field of application.
