PEEK (Polyetheretherketone) – properties & applications

PEEK (Polyetheretherketone) is a semi-crystalline, thermoplastic high-performance material, and is characterised mainly by its very good mechanical properties and exceptional dimensional stability, even at high continuous operating temperatures of up to 250°C. Due to their properties, PEEK plastics are suitable for a wide range of applications with demanding operating conditions.

PEEK properties at a glance:

• Very high temperature resistance (up to 250°C continuous operating temperature)
• Excellent chemical resistance
• Good dimensional resistance (low thermal expansion)
• Optimal ratio of stiffness, solidity, toughness and minimal tendency to creep
• Very good tribological properties (good sliding performance, low wear)
• Good radiation resistance
• Excellent resistance to hydrolysis
• Fire performance: flame-retardant, Low smoke density, No toxic gases
• Good machinability
• Good bondability and weldability
