PEEK (polyetheretherketone)

PEEK is generally considered to be one of the best performing thermoplastics in the world. PEEK offers exceptional performance over a wide range of temperatures and extreme conditions. PEEK has a unique combination of thermal, mechanical and chemical resistance properties. PEEK can withstand a continuous working temperature of 250°C and has an excellent long-term chemical resistance.

Key properties

• Very good chemical resistance
• Excellent strength, rigidity and toughness at elevated temperatures
• FDA approved
• Low permeability
• Low moisture absorption
• Low coefficient of friction
• Excellent electrical properties
• Working temperature from -40°C to +250°C (short periods +310°C)
Properties of PEEK can be improved by adding additives as carbon, glass etc.


• PEEK tubing
• PEEK bushes
• PEEK rings
• PEEK rod
• PEEK pipe
• PEEK film
• PEEK sheet
• PEEK fibre
• Filled: glass, carbon or a combination of carbon/graphite/PTFE
