Association of antioxidant-added highly cross-linked polyethylene on revision risk: a registry-based study of 198,073 total hip replacements from the Australian Orthopaedic Association National Joint Replacement Registry between 2014 and 2023 [PDF]

Acta Orthopaedica
Background and purpose: Adding antioxidant to highly cross-linked polyethylene (XLPE) is proposed to improve oxidation resistance and decrease wear in total hip replacements (THR), but long-term performance is unknown.

Mechanically Triggered Chemical Recyclable Polyethylene-Like Materials. [PDF]

Angew Chem Int Ed Engl
Polyethylene‐like copolymers with benchmark properties are prepared by embedding latent cyclobutene mechanophores to overcome PE's end‐of‐life limits. The mechanophores are inert in service but are selectively opened by solvent‐free ball milling to yield well‐defined telechelic oligomers.

Effect of Aggregation Structure on DC Electrical Performance of Thermo‐Oxidatively Aged Crosslinked Polyethylene Insulation

High Voltage
Thermal ageing is an important factor leading to the deterioration of crosslinked polyethylene (XLPE) cable insulation. In this paper, XLPE insulating material was prepared in the laboratory and treated by thermal ageing at 130°C for durations of up to ...

Polyamide 12 Filled with Cross-Linked Polyethylene Waste: Processing, Compatibilization, and Properties [PDF]

Materials Research, 2023
Cross-linked polyethylene (XLPE) is primarily used as a coating and insulator for electrical wires and cables. The cross-links render recycling through remelting unfeasible, and XLPE waste is usually incinerated or sent to landfills.

Crosslinked Polyethylene (XLPE) Recycling via Foams

Polymers, 2022
Efficient recycling of crosslinked polyethylene has been challenging due to manufacturing difficulties caused by chemical crosslinking. This study focuses on simple processing via solid waste powder generation and particle fining for the subsequent crosslinked polyethylene inclusion and dispersion in rigid polyurethane foam.
