Peek

Peek (polyetheretherketone) is a high performance thermoplastic known for its exceptional mechanical properties, chemical resistance and ability to withstand high temperatures. Peek is used in various demanding applications across industries such as aerospace, automobile, medical and oil and gas. It is a sustainable material due to its recyclability and ability to replace traditional materials reducing environmental impact.

Key characteristics

• High temperature resistance, withstanding continuous high temperatures up to 250°C and even higher temperatures for short periods.
• Excellent mechanical strength, offering high strength and stiffness even at elevated temperatures and exhibits good creep and fatigue resistance.
• Chemical resistance – highly resistant to a wide range of chemicals, including acids, alkalis and organic solvents.
• Displays excellent wear resistance and low friction, making it suitable for tribological applications.
• Dimensional stability – maintains its dimensions well under various temperatures and loads
• Highly resistant to high energy radiation, such as gamma and x-rays.
• Inherently low in flammability and emits minimal smoke when exposed to fire.
• FDA approved – unfilled peek is approved by the FDA for food contact applications.

Applications

• Aerospace – peek is used in aircraft components, including engine parts and interior fittings due to its strength, weight and fire resistance.
• Automotive – peek is employed in various automotive parts, such as gears, bearings and seals, where high performance and durability are crucial.
• Medical – peek is biocompatible and is used in implants, surgical instruments and other medical devices.
• Peek’s chemical resistance and ability to withstand high pressures and temperatures make it suitable for downhole and other demanding oil and gas applications.
• Electronics – peek is used in electronic components, including connectors, insulators and substrates for flexible circuits.
