Wear Reduction Over Conventional Polyethylene at 100 Million Cycles.²

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.³

The oxidative stability of Vivacit-E HXPE is the result of a proprietary process that grafts (locks) vitamin E directly to the polyethylene chain. ^4,,6,7

The vitamin E continuously stabilises the material to prevent oxidative degradation of the polyethylene.

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.^3,,

In tests on two week-aged 40mm articulation size Vivacit-E liners and Longevity liners, Vivacit-E liners showed ultra-low wear rates comparable to Longevity liners.
