E1™ Antioxidant Infused Technology
The only polyethylene infused with vitamin E to provide strength
and oxidative stability without compromise
E1™ Antioxidant Infused Technology surpasses the limitations of first generation highly crosslinked polyethylene. This unique technology, developed by Biomet’s engineers and the research power of Massachusetts General Hospital, is the first vitamin E stabilized highly crosslinked polyethylene bearing material that has been shown in testing to provide high mechanical strength and true oxidative stability.
- Produced using a patent pending second-generation technology and proprietary process1
- Isostatically compression molded polyethylene barstock, as used in clinically proven ArCom® polyethylene, is processed below the melt temperature to maintain the strength of the crosslinked polyethylene
- Infused with vitamin E to stabilize free radicals and prevent oxidative degradation
- Fatigue strength greater than first generation re-melted HXLPE1-3
- Stronger than sequentially crosslinked and annealed materials after an environmental stress cracking (ESC) study1
- True oxidative protection without re-melting: no evidence of measurable oxidation1
