PEEK resin is an ideal electrical insulator. It can still maintain good electrical insulation performance under harsh working conditions such as high temperature, high pressure and high humidity. Therefore, the field of electronic information has gradually become the second largest application field of PEEK resin, manufacturing and transporting ultra-pure water The pipelines, valves and pumps are commonly used in the semiconductor industry to manufacture wafer carriers, electronic insulating diaphragms and various connecting devices. As a semi-crystalline engineering plastic, PEEK is insoluble in almost all solvents except concentrated sulfuric acid, so it is often used to make compressor valves, piston rings, seals, and various chemical pump bodies and valve parts.
