Polyetheretherketone (PEEK) is a high-performance thermoplastic polymer known for its excellent mechanical and thermal properties. It is resistant to chemicals, high temperatures, and wear, making it suitable for demanding applications in industries such as aerospace, automotive, and medical. PEEK can withstand continuous use at temperatures up to 260°C (500°F) and has a high strength-to-weight ratio. Its biocompatibility allows for use in medical implants and devices. Additionally, PEEK can be processed through various methods, including injection molding and 3D printing, enabling versatile manufacturing options.
