Due to its good mechanical properties, chemical resistance, radiation resistance and high temperature resistance, PEEK can withstand up to o. The pressure of 25 MPa and the high temperature of 260 ° C are insoluble in all solvents except concentrated sulfuric acid. In the chemical industry and other industries, PEEK resin is commonly used to make compressor valve discs, piston rings, seals and various chemical pumps, valves and other components; using this material instead of stainless steel to make the impeller of the vortex pump can significantly reduce the degree of wear And noise level for a longer life.
Wire and cable and coil bobbins made of PEEK have been successfully applied to nuclear power plants, and can also be used for functional probes of special geometries of petroleum exploration and mining machinery.
In addition, modern connectors will be another potential application market because PEEK resins meet the specifications of the casing assembly materials and can be bonded using various adhesives at high temperatures. The electrical and electronic field has gradually become the second major application field of PEEK resin. Because of its excellent electrical properties, it is an ideal electrical insulating material. It can still maintain good performance under harsh working conditions such as high temperature, high pressure and high humidity. Electrical insulation. The PEEK resin itself is highly pure and mechanically and chemically stable, which reduces the contamination of the wafer during processing. Due to the high purity, pipes, valves and pumps made of polyetheretherketone resin can prevent ultrapure water from being contaminated during transport when transporting ultrapure water.
