Research on the charge transportation mechanism of cross-linked polyethylene (XLPE) with Al electrode and semi-conductive screen

IOP Conference Series: Materials Science and Engineering, 2019
To study the effects of the different electrodes on the charge transport mechanism in XLPE, the conductive currents of cross-linked polyethylene (XLPE) with Al electrode and semi-conductive screen have been compared. And the currents of the two kinds of samples at low electric field, which are tested after not injecting and injecting space charge.

Total hip replacements with bearings with cross-linked polyethylene

Zdravniški Vestnik, 2009
Introduction: Polyethylene has excellent properties as a bearing material for total joint replacements, though it also has some shortcomings. Polyethylene wear debris leads to a biological response, osteolysis and aseptic component loosening.

Polarity-Dependent DC Dielectric Behavior of Virgin XLPO, XLPE, and PVC Cable Insulations

Energies
Reliable DC cable insulation is crucial for photovoltaic (PV) systems and high-voltage DC (HVDC) networks. However, conventional materials such as cross-linked polyethylene (XLPE) and polyvinyl chloride (PVC) face challenges under prolonged DC stress ...

Effect of Functionalized Graphene Oxide with Hyper-Branched Flame Retardant on Flammability and Thermal Stability of Cross-Linked Polyethylene [PDF]

, 2014
In this work, GO was functionalized by a hyper-branched flame retardant, which was synthesized by the reaction of N-aminoethyl piperazine and di(acryloyloxyethyl)methylphosphonate. Subsequently, the resultant functionalized GO (FGO) was incorporated into
