IMPEKK®, implantable Poly-Ether-Ketone-Ketone polymer
IMPEKK® is designed for permanent surgical implants such as spinal, cranial, orthopedics, dental and is extremely suitable for Additive Manufacturing.
Poly-Ether-Ketone-Ketone chemical structure

properties of impekk®
- Elastic modulus close to cortical bone
- X-ray translucency
- Chemical inertness
- Outstanding compressive strength
- Toughness
- Sterilizable
The presence of an additional ketone group gives IMPEKK® polymer greater polarity and allows a better acceptance of functional fillers, providing a wide range of formulation choices for implantable medical device manufacturers. IMPEKK® polymer is composed of ether (flexibilizing) and ketone (rigidifying) groups. The more ketone groups there are, the higher the Tg (Glass Transition temperature) and the better the mechanical properties. IMPEKK® is a copolymer that includes terephthaloyl and isophthaloyl units. This modularity allows fine tuning of crystallization rate and melting point temperature (Tm).
