A Lifetime of Wear Resistance
Wear Reduction Over Conventional Polyethylene at 100 Million Cycles2
Oxidation or Significant Decline in Mechanical Properties
When subjected to accelerated aging for 33 weeks7
Exceptional Oxidative Stability
- It’s widely accepted that oxidation is a primary aging mechanism of polyethylene, which can lead to osteolysis and implant failure. The oxidative stability of Vivacit-E HXPE is the result of a proprietary process that grafts (locks) vitamin E directly to the polyethylene chain.3-6 The vitamin E continuously stabilizes the material to prevent oxidative degradation of the polyethylene. When subjected to accelerated aging for 33 weeks (16 times the industry standard), Vivacit-E HXPE showed no signs of oxidation or significant decline in mechanical properties.7
- In tests on 2 week-aged 40 mm articulation size Vivacit-E liners and Longevity liners, Vivacit-E liners showed ultra-low wear rates comparable to Longevity liners.8
- Antioxidant protection eliminates the need to remelt the polyethylene, leading to an improvement in strength in comparison to highly crosslinked polyethylene.9
- The vitamin E in Vivacit-E HXPE prevents oxidation, resulting in mechanical strength that is retained after accelerated aging for more than 16 times the 2-week industry standard test according to ASTM F2003.7,9,10
