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. It is composed of ether (flexibilizing) and ketone (rigidifying) groups. Our IMPEKK® range possesses multiple properties such as chemical inertness, an elastic modulus close to cortical bone, an outstanding compressive strength and more. Furthermore, IMPEKK® is particularly designed for Additive Manufacturing.

SEQENS unique offer is composed of:

  • IMPEKK® granules for testing and development with IMPEKK® 1G-T
  • IMPEKK® filament for testing with IMPEKK® 3D-F-T
