Mitsubishi Chemical Group Advanced Materials - MediTECH

Zeniva® PEEK is a high-performance specialty polymer with high strength and advanced stiffness that offers extreme toughness and reliability for use in structural, load-bearing implantable medical devices. This bio-stable plastic has excellent fatigue and creep resistance. The unique properties of Zeniva® PEEK allow implantable devices to withstand continuous strain and repeat loading. 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 that allow X-ray and CT scanning procedures without interference.

The MediTECH® Division at Mitsubishi Chemical Group Advanced Materials exclusively processes raw materials from Solvay SA for Zeniva® PEEK. These are fully conform with ASTM F2026 guidelines.

Typical orthopaedic implants:

• Spinal - spinal cages and spacers for anterior and posterior lumbar interbody fusions
• Supports fixations in anterior and posterior cervical interbody fusions and disc height restoration
• Suture anchors and bone screws
• Dental
• Trauma and large joints

Ultra-high molecular weight polyethylene (UHMW-PE) is manufactured and supplied by the MediTECH® Implantable Polymers division as thermoplastic shapes to be used in orthopaedics implants. As a polyethylene with a very specialized molecular weight, UHMW-PE is produced as a powder that requires special processing. In the shapes industry, the high pressures generated for Chirulen® UHMW-PE compression molding and for Extrulen® UHMW-PE ram extrusion processes fuse the particles together that is then formed into stock shapes or profiles. 

UHMW-PE product benefits:

• Exceptionally high notched impact strength
• High energy absorption capacity at high stress rate
• Excellent wear resistant properties
• Low coefficient of friction

Typical orthopedic implants:

• Shoulder
• Elbow
• Knee
• Ankle
