EXp™ Polyethylene Technology

EXp™ Polyethylene Technology represents an optimal blend of UHMWPE, the antioxidant vitamin E(α-tocopherol), and cross-linking for long-term oxidative stability, preservation of mechanical properties and performance.

  • Unlike other highly cross-linked polyethylenes, EXp requires no thermal processing or infusion of antioxidants to stabilize the material.
  • EXp liners experienced no failures as a result of dynamic impingement testing.
  • The vitamin E blended into the EXp does not elude from the material during extraction studies.
  • The morphology of EXp UHMWPE is consistent with conventional UHMWPE—demonstrating no consolidation defects or voids.
