The long-term use temperature of polyetheretherketone is as high as 250°C, so it was once called a super heat-resistant special engineering plastic. In addition, it also has excellent comprehensive properties such as high strength, corrosion resistance, radiation resistance, excellent electrical properties, flame retardancy, and adaptability to various chemical processing techniques. Therefore, PEEK has been widely used in high-tech fields such as national defense industry, aerospace, electronic information, energy, automobiles, home appliances, and medical and health care.
