Current‐Generation Crosslinked Polyethylenes for Total Hip Arthroplasty: Mechanistic Insights Into Oxidative Stability and Antioxidant Efficiency

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 114, Issue 7, July 2026.
ABSTRACT Highly crosslinked polyethylene (XLPE) has revolutionized total hip arthroplasty (THA), but increased radiation doses and complex crosslink structures may increase oxidation susceptibility. The long‐term oxidative stability of XLPE depends on manufacturing factors, including crosslink density, antioxidant (vitamin E) concentration ...

Evaluation of Moisture Ageing Status of Cross‐Linked Polyethylene Insulation in Power Cables at Different Temperatures

High Voltage, Volume 11, Issue 2, Page 410-420, April 2026.
ABSTRACT Cross‐linked polyethylene (XLPE) cables play an important role in power systems to transport electrical energy, and moisture is one of the important predisposing factors for insulation failure in medium and high‐voltage cables. In this paper, a temperature‐moisture accelerated ageing experiment is designed, and a method for assessing the ...
