Introducing E1™ Antioxidant Infused Technology
.jpg)
As just one of a number of initiatives to harmonise Global branding of Biomet products, E-Poly™ HXLPE is undergoing a name change to E1™ Antioxidant Infused Technology.
Same great technology, new name
E1™ Antioxidant Infused Technology will continue to enjoy the same benefits of E-Poly™ HXLPE simply under its new name of E1™ Antioxidant Infused Technology. Consequently, E1™ remains the first polyethylene to address the limitations associated with remelting and annealing1-4 by utilising vitamin E free radical stabilisation methods. This means E1™ will continue to offer the following benefits:
• Substantially reduced wear rates5
• Greater strength than re-melted polyethylenes5-7
• True oxidation protection5,8
The only changes you will see are the name reflected on product labelling and upon the product literature, which will be rolling-out into hospitals shortly. Local Biomet representatives will be working with surgeons and hospital teams to minimise any confusion caused during this interim period.
What does E1™ Antioxidant Infused Technology mean to you and Biomet:
• E1™, the 1st Vitamin E Stabilised Polyethylene
• E1™, the 1st polyethylene to use antioxidant infusion processing
• E1™, the #1 in polyethylene articulation technology
