E1

E1^™ Antioxidant Infused Technology, the first vitamin E stabilized highly crosslinked polyethylene bearing material, is unlike any other polyethylene currently available for joint replacement.

• Biomet's E1^™ Antioxidant Infused Technology is a second generation material that has been shown in testing to provide high mechanical strength and oxidative stability.¹

• E1^™ Antioxidant Infused Technology can provide an optimal combination of acetabular fixation and low wear1 when used with the Regenerex™ RingLoc^®+ Modular Shell.

• The liners are available in 28mm, 32mm and 36mm inner diameters.

The key benefits of E1^™ Antioxidant Infused Technology include:
• Higher levels of crosslinking for better wear performance
• Greater strength than first generation remelted HXLPE^1-3
• True oxidative protection without remelting¹

The E1^™ Antioxidant Infused Technology Process

Surpassing the limitations of first generation highly crosslinked polyethylene, E1^™ Antioxidant Infused Technology is truly a unique technology developed by Biomet's engineers and the research power of Massachusetts General Hospital.

• Produced using a patent pending second-generation technology and proprietary process.
• 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.

Testing has shown that E-Poly™ HXLPE offers:
• Ultra-low wear rates with large heads: 95 percent wear reduction when comparing 40mm E1^™ liners to 36mm ArCom^® liners and 99 percent wear reduction with smaller femoral heads when compared to already low ArComXL^® polyethylene.¹
• Fatigue strength greater than first generation re-melted HXLPE.^1-3
• Stronger than sequentially crosslinked and annealed materials after an environmental stress cracking (ESC) study.¹

True oxidative protection without re-melting: no evidence of measurable oxidation.¹
