DePuy Synthes Joint Reconstruction, a leader in researching and producing polyethylene, is proud to offer the next generation of polyethylene, AOX™ Polyethylene. This advanced material, introduces a unique antioxidant, COVERNOX™ Antioxidant, which combines with post irradiation free radicals to stabilize them. Once implanted, the COVERNOX™ Antioxidant which has bonded with free radicals, prevents oxidation to maintain mechanical integrity and oxidative stability.
|Oxidative Stability||• The polyethylene resin is blended with an antioxidant (COVERNOX Antioxidant). The antioxidant stabilizes free radicals preventing them from oxidizing.|
|Wear Resistance||• The polyethylene resin/COVERNOX Antioxidant mix is exposed to a level of irradiation (8 Mrads) to stimulate a moderate amount of cross-linking while delivering optimum wear characteristics without compromising mechanical integrity.|
• AOX Polyethylene maintains high material strength and toughness characteristics by utilizing GUR 1020 resin, with its better inherent mechanical properties, than GUR 1050.1
• The addition of an antioxidant into the material eliminates the need for re-melting or annealing, and therefore it maintains excellent mechanical properties.2
