The power to lock out oxidative wear

The power of ECiMa technology The next generation vitamin E-enriched technology, ECiMa is one of the most advanced polyethylenes of its kind, providing a high performance alternative to hard bearings. ECiMa is highly cross-linked using cold-gamma irradiation. The blended vitamin E resin is mechanically annealed to give a uniform direct compression molded polyethylene. This allows chemical bonding of the antioxidants right at the start of the polyethylene’s life cycle. In a process designed to avoid the negative impact of thermal remelting and increase material strength, ECiMa delivers a biocompatible,...

The next generation vitamin E technology

ECiMa encompasses the four key elements needed to take the innovative step forward in high performance bearing technology. Ultra low wear Designed to maximise survivorship, ECiMa test results indicate ultra low wear rates1 with the potential to reduce wear-related osteolysis in vivo, even with 40mm bearings. • 95% reduction compared to UHMWPE • 83% reduction compared to HXLPE Wear rate1 Mechanical superiority A new benchmark in mechanical performance, ECiMa technology offers improved mechanical strength over first generation vitamin E polyethylene and early HXLPE liners providing: • • • • reduced...

Oxidative shield The free radical stabilization effect of vitamin E provides a natural barrier to potential long-term oxidation which can occur in vivo – test results show no evidence of oxidation following intensive ageing and cyclic loading in vitro where previous HXLPE liners have failed.
