Superior Oxidative Stability

Blending the vitamin E prior to consolidation allows the antioxidant to distribute uniformly throughout the material.

Improved Wear Resistance

A patented gamma irradiation and mechanical annealing process, tailored to the vitamin E content, is used to achieve the desired crosslink density. This highly crosslinked polyethylene yields a reduced wear rate compared to conventional polyethylene.5

Optimized Mechanical Strength

Unlike remelted polymers, the proprietary XLE polyethylene mechanical annealing process quenches free radicals below the melt temperature, which maintains the crosslink density and provides enhanced mechanical strength over conventional polyethylene.9
