Electrofusion Welding of Cross-Linked Polyethylene Pipes
, 1997 Fatigue and squeeze tests have been undertaken to investigate if electro- fusion couplers can be used to joint cross-linked polyethylene pipes . Two types of polyethylene pipes, each with 63 mm outside diameter and 5 .8 mm wall thickness, are irradiated ...

Kinetic modelling of phenols consumption during polyethylene thermal oxidation [PDF]
, 2013 Irganox 1010 stabilized PE was monitored by carbonyl build-up and DSC under oxygen. A scheme for PE stabilization by phenols was implemented and its kinetic parameters were calculated from experimental results.

Massive Osteolysis in a Modern Total Knee Prosthesis
Case Reports in Orthopedics, 2021 Case. An 82-year-old woman underwent right total knee replacement with a sequentially irradiated and annealed highly cross-linked polyethylene insert. At 9 years, she was found to have a massive femoral osteolysis with an impending fracture.

Early failure of sequentially annealed polyethylene in total knee arthroplasty
Arthroplasty Today, 2020 Improvements in the processing of polyethylene have led to a dramatic reduction in wear rates in total hip arthroplasty. This led to the adoption of modern highly cross-linked polyethylene in total knee arthroplasty (TKA).

Wear Tests of a Potential Biolubricant for Orthopedic Biopolymers [PDF]
, 2015 Most wear testing of orthopedic implant materials is undertaken with dilute bovine serum used as the lubricant. However, dilute bovine serum is different to the synovial fluid in which natural and artificial joints must operate. As part of a search for a

Mobility‐limited charge injection in cross‐linked polyethylene under extra high electric field
High Voltage, 2021 In this study, characteristics of charge injection under extra high electric field (above 100 kV/mm) in cross‐linked polyethylene (XLPE) were investigated by experiments of conduction current and space charge.
