E1® Antioxidant Infused Technology
The only polyethylene infused with vitamin E to provide strength
and oxidative stability without compromise

Infused with vitamin E, a natural antioxidant, E1® Technology defines a new class of bearings and overcomes the limitations of remelted and annealed polyethylenes by uniting true oxidative stability, high mechanical strength and ultra-low wear.1

The benefits of E1® technology have been validated as Biomet is the only orthopedic device manufacturer that offers a bearing with the following FDA cleared claims (in italics):

Oxidative Stability
  • “E1® Antioxidant Infused Technology prevents oxidative degradation of polyethylene.”1
  • “E1® Antioxidant Infused Technology protects polyethylene from oxidation and cracking during environmental stress crack testing.”1
  • E1® Antioxidant Infused Bearings maintain mechanical properties and wear resistance over time.1
Mechanical Strength
  • “E1® Antioxidant Infused Technology maintains the mechanical strength of conventional UHMWPE under small punch testing.”1
  • “E1® Antioxidant Infused Technology maintains mechanical strength after accelerated aging.”1
  • Unlike many highly crosslinked polyethlylenes, E1® material is never remelted and therefore maintains its strength.1,2
Ultra-low Wear
  • 100 kGy irradiation results in high levels of crosslinking for wear resistance.1
  • Cruciate Retaining (CR) E1® Tibial Bearings had a wear rate that was 86% less than conventional direct compression molded polyethylene.1
  • Posterior Stabilized (PS) E1® Tibial Bearings had a wear rate that was 87% less than conventional direct compression molded polyethylene.1
