E-Poly™

Moving Beyond Simple Wear Reduction

E-Poly™ HXLPE, the first vitamin E stabilized highly crosslinked polyethylene bearing material, is unlike any other polyethylene currently available for joint replacement.

• Biomet's E-Poly™ HXLPE is a second generation material that has been shown in testing to provide high mechanical strength and oxidative stability.1

• E-Poly™ HXLPE 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 E-Poly™ HXLPE include:
• Higher levels of crosslinking for better wear performance
• Greater strength than first generation remelted HXLPE1-3
• True oxidative protection without remelting1

The E-Poly™ HXLPE Process

Surpassing the limitations of first generation highly crosslinked polyethylene, E-Poly™ HXLPE 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 E-Poly™ 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
