PEEK (polyether ether ketone) is a high-performance, engineering-grade thermoplastic known for its exceptional strength, thermal stability, and chemical resistance. It maintains mechanical properties at temperatures up to 250 °C (480 °F), making it ideal for high-temperature applications. PEEK offers high wear resistance, excellent dimensional stability, and is inherently self-lubricating, which reduces the need for additional coatings. It is resistant to a wide range of chemicals, including acids, bases, and organic solvents. Due to these remarkable properties, PEEK is used extensively in demanding industries such as aerospace, automotive, medical devices, and electronics. Components made from PEEK include bearing inserts, gears, seals, valve components, and high-performance insulators. It can also be used in 3D printing and CNC machining for producing precision parts in industrial and medical environments.
