Corin’s most advanced polyethylene enriched with antioxidant vitamin E, designed to provide an alternative to hard bearings.
In mobile joint replacement, minimising wear is critical to longevity.
ECiMa has excellent wear properties thanks to extensive cross-links created during an optimised, cold gamma irradiation process1. When compared to UHMWPE and HXLPE, a 95% and 83% reduction in wear rate was recorded2.
After cross-linking, some free radicals may remain. Removing these reactive free radicals is critical.
Corin use a proprietary mechanical annealing process to reduce free radicals created during the irradiation process without re-melting. This means crystallinity is largely unaffected and ECiMa retains the proven mechanical strength and performance of UHMWPE3.
An optimised dosage4 of vitamin-E is blended with UHMWPE before consolidation to provide uniform, long term resistance to oxidation2,5,6,7.
This vitamin-E reduces oxidation initially by neutralising reactive free radicals created during irradiation, and a remaining antioxidant reservoir provides active stabilisation to minimise in vivo oxidation.
