January 27, 2025Polyether ether ketone (PEEK) is a high-performance engineering thermoplastic known for its outstanding wear resistance and ability to perform under demanding conditions.

What are the wear properties of PEEK?
- Low Friction Coefficient:
PEEK exhibits a low coefficient of friction, reducing the energy loss during sliding or rotational movements. This makes it ideal for applications such as bearings, gears, and bushings. - High Wear Resistance:
PEEK has excellent wear resistance, even under high loads and temperatures, ensuring a longer service life compared to other polymers. This property is particularly valuable in environments where continuous mechanical interaction occurs. - Exceptional Abrasion Resistance:
PEEK is highly resistant to abrasive wear, allowing it to maintain dimensional stability and surface integrity when exposed to harsh or abrasive surfaces. - Performance at Elevated Temperatures:
PEEK retains its wear resistance and mechanical properties at temperatures up to 250°C, making it suitable for high-temperature environments like automotive and aerospace industries. - Chemical Resistance During Wear:
PEEK maintains its wear properties even when exposed to chemicals, oils, or solvents, making it ideal for chemically aggressive environments. - Self-Lubricating Grades:
Some PEEK composites, such as those filled with PTFE or graphite, offer enhanced self-lubricating properties, further reducing wear and friction without the need for external lubrication. - Fatigue Resistance:
PEEK demonstrates excellent fatigue resistance under cyclic loading, ensuring its longevity in applications involving repetitive motion.
PEEK’s outstanding wear properties make it a preferred material in demanding industries, including automotive, medical, and oil and gas.
