Oxidation Profile1,3
After ESC testing
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.1,2
Oxidative Stability
Testing has shown that vitamin E prevents
oxidative degradation of the polyethylene
without remelting, allowing the material to
maintain mechanical properties and wear
resistance over time.1
87 percent (posterior
stabilized) wear reduction
over conventional Direct
Compression Molded
polyethylene in the knee1
Mechanical Strength
E1™ material is never remelted
and therefore maintains its strength.1,2
It is also stronger than sequentially
crosslinked and annealed materials after
fatigue testing in an accelerated aging
environment (environmental stress
crack testing).1
Ultra Low Wear
10 Mrad (100 kGy) irradiation results
in high levels of crosslinking for
wear resistance.1
