Vivacit-E HXPE
Conventional PE
Through a proprietary process, Vivacit-E HXPE results in a technologically advanced material that ensures all of the desired polyethylene characteristics are maximized, with no compromises.
Enhanced Grafting Technology1,2
• To prevent oxidation, Zimmer has developed a process which facilitates a phenomenon called “Grafting”
• Efficiently grafts (locks) 75-90% of Vitamin-E to the polyethylene chain
• Ensures durability and longevity of the polyethylene long-term

Grafted Vitamin E Protection
The Vitamin E is grafted (locked) directly to the polyethylene chain5-7 to prevent elution for long-term oxidative protection.
