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).
