Zeniva® PEEK
Zeniva® PEEK is a high-performance, biocompatible polymer used primarily for orthopedic, cardiac and neurological implantable devices. It has a modulus very close to that of cortical bone plus excellent fatigue resistance and toughness. In addition, it offers numerous advantages over metals, such as a reduction of stress shielding, no heavy metal allergy or ion erosion, and has
radiolucent properties which allow x-ray
and CT scanning procedures without interference.
Long-term Implantation | Key Application Segment: Spinal Fusion Cages
Zeniva® PEEK is offered for use in implantable medical devices that are meant for long-term implantation.
Performance benefits of Zeniva® PEEK shapes include:
These shapes are ideal for the close tolerance machining of finished components, and for prototypes used in injection molding applications.
Zeniva® PEEK resin and stock shapes comply with ISO 13485 manufacturing standards and meet current Good Manufacturing Practices (GMP). Based on rigorous biocompatibility testing, these products demonstrate no evidence of cytotoxicity, sensitization, irritation, or acute systemic toxicity as defined by ISO 10993. These products can be sterilized using all conventional methods, including gamma radiation, ethylene oxide, and steam.

Cross-linking
Chirulen® and Extrulen® are the market leading products for use in today's highly cross-linked Polyethylenes (XL-PEs). Clinical results and studies demonstrate significant improvements achieved in wear reduction and further improvements are in constant development.
Mitsubishi Chemical Advanced Materials dedicates a considerable portion of their R&D efforts and know-how to the development of customized XL-PEs, also in combination with Vitamin E and other antioxidants.

1 = penetration depth of electrons 5 = Co-60 Irradiation source
2 = primary electrons (source) 6 = ϒ-quanta
3 = secondary electrons
4 = irradiated material
Antioxidants
Our products are completed by antioxidant additives like Vitamin E, HALS, customer antioxidants and others.
Example: Vitamin E
Sterilization and cross-linking by irradiation bear the risk of free radicals formed in the UHMW-PE which can result in in vivo oxidation and material degradation.
Vitamin E known as an antioxidant has positive influence on this process and is used as a stabilizer for orthopaedic implants made from UHMW-PE.
Mitsubishi Chemical Advanced Materials provides Chirulen® and Extrulen® shapes with Vitamin E as per customers' requirements. Tests have proven unaffected biocompatibilty of medical grade UHMW-PE blended with Vitamin E, as well as show mechanical properties to remain practically unchanged.
Life Science Grades
Mitsubishi Chemical Advanced Materials has a long history of developing, manufacturing, and supplying engineering plastics used in Medical and Life Science applications. We work closely with medical device manufacturers to support them in selecting the best polymer for their biomedical application.
