PEEK offers a unique combination of mechanical, chemical, electrical, and thermal properties.

- PEEK is a semi-crystalline, high-performance engineering thermoplastic.

- Crystallinity imparts excellent resistance to a wide range of liquids. It also offers superb fatigue performance.

- PEEK is insoluble in all common solvents and does not undergo hydrolysis.

- PEEK has an excellent sterilization resistance at high temperature.

- PEEK has good dimensional stability, inherent purity, and biocompatibility.

Thermal properties

- High Melting Point (Tm), 343°C

- High Glass Transition (Tg) temperature, 143°C

- High continuous service temperature, up to 260°C

Electrical properties

- PEEK polymer exhibits high volume resistivity and surface resistivity.

- PEEK maintains good insulating properties in a broad temperature range and environmental changes.

Flammability
