The Chinese name of PEEK is polyether ether ketone. It is a special engineering plastic with excellent performance. PEEK has a series of excellent comprehensive properties such as high temperature resistance, wear resistance, corrosion resistance, high strength, etc. It is widely used in aerospace, automotive manufacturing, electrical and electronic, medical and food processing and other fields.
Its characteristics are as follows:
PEEK, as the base material, adding carbon fiber 30% and PTFE resin with sliding characteristics of graphite and produced, improves the high sliding grade, as "bearing grade PEEK material" (color: black). Its superior friction characteristics (low friction, long term wear resistance, and pressure-velocity capability) make it ideal for applications where wear is common.
PEEK is widely used in nuclear industry, chemical industry, aerospace, automobile manufacturing, electronic appliances, mechanical instruments, medical treatment and food processing, especially as a thermoplastic resin with excellent heat resistance. It can be used as the base material of high-performance composite materials.
Polyether etherketone, or polyethertherketone (PEEK for short), is a linear aromatic polymer with a chain in its main chain. Its constituent unit is oxygen-p-phenyl-oxygen-carbonyl-p-phenyl, is semi-crystalline, thermoplastic plastics. It is a thermal plasticity resin with excellent mechanical properties and crystallization, excellent heat resistance, fatigue resistance, impact resistance and creep resistance, chemical resistance is possible to use except concentrated sulfuric acid, and less pure material for dissolution of gas metal ions. In addition, welding processing is also possible for materials with a wide range of uses being used.
Polyether ether ketone has excellent performance, and its application fields will be more extensive along with domestic application research. At present, Chongqing 973 New Materials Research Center has been specially established in China, which is specialized in PEEK in the application field research. he research center was established under the leadership and care of Chongqing municipal governments at all levels. It is committed to the research in the field of automobiles, electronic appliances, transportation and other fields, and is at the forefront of applied research in China at present.
