PEEK (Polyetheretherketone) is a semicrystalline thermoplastic with outstanding mechanical properties, making it indispensable across various engineering applications. With exceptional temperature resistance and mechanical strength, PEEK is preferred for components operating in demanding environments subjected to high temperatures, pressures, and mechanical stresses. Its remarkable wear resistance and low coefficient of friction make it ideal for applications requiring prolonged exposure to friction and sliding movements.
