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

 - PEEK has a V0 flammability rating down to 1.45 mm.
 - PEEK has a Limiting Oxygen Index (LOI) of 35%.
 - Smoke emission and toxic gas generation is extremely low.
