E1® Antioxidant Infused Polyethylene


Zimmer Biomet's E1® Antioxidant Infused Technology is the only bearing option that utilizes a proprietary diffusion process to maxamize strength, wear resistance and prevent oxidative degradation of the polyethylene.

Vitamin E, a natural antioxidant, stabilizes free radicals, preventing oxygen from reacting with the polyethylene. This allows Zimmer Biomet’s hip bearings with E1 Antioxidant Infused Technology to prevent oxidative degradation of polyethylene2*, overcome the limitations of remelted and annealed polyethylenes by uniting oxidative stability with high mechanical strength and ultra-low wear.1,3

E1 Antioxidant Infused Technology:

  • Prevents oxidative degradation of polyethylene2*
  • Maintains high strength because it does not remelt1
  • Provides wear rates similar to metal-on-metal run-in wear3,4
  • Available in head sizes up to 44 mm
  • Developed from clinically proven ArCom® polyethylene5
