Due to peek having good mechanical properties, chemical resistance, radiation resistance and heat resistance, it can withstand up to 0.25Mpa pressure and high temperature of 260 ℃, while insoluble in all solvents except concentrated sulfuric acid. In the chemical industry and other industries, PEEK resin used to produce compressor valves, piston rings, seals and a variety of chemical pumps, valves and other components; using this material instead of stainless steel vortex pump impeller, can significantly reduce the degree of wear and tear and the noise level, has a longer service life. Currently with PEEK production of wire and cable, coil skeleton, have been successfully used in nuclear power plants, but also for petroleum exploration and production of special mechanical geometry function probe. Further, since the PEEK resin complies with specifications cannula assembly materials at high temperatures can still use a variety of adhesive bonding, so its modern connector will be another potential application market.
