ecimaVitamin E

Vitamin E is blended and consolidated with UHWPE powder providing uniform distribution of the antioxidant

  • Vitamin E acts as a reservoir for active stabilisation
  • Vitamin E prevents free radical oxidation into the long-term1,2,3,4

Cold Gamma irradiated

Engineered and specific process excites molecules to create cross links

  • Improved wear resistance of the material 1,2,3,4
  • Optimised dose of irradiation 5

Mechanical annealing

Material is heated below the melting point maintaining crystallinity

  • High strength properties
  • Anti-oxidative process
