PEEK is widely used in the aerospace industry due to its excellent strength-to-weight ratio and resistance to high temperatures. It is commonly employed in the manufacture of aircraft components such as brackets, seals, and insulation. In the medical field, PEEK is utilized for implants and surgical instruments because of its biocompatibility and ability to withstand sterilization processes. The automotive industry benefits from PEEK in the production of lightweight, durable parts like bearings and seals, which enhance fuel efficiency. Additionally, PEEK is used in the electronics sector for connectors and insulating components, thanks to its electrical insulation properties and resistance to harsh environments. Its chemical resistance also makes it suitable for use in industrial applications, including pumps, valves, and compressor plates, where it performs reliably in corrosive conditions.
