Etching and the Morphology of Cross-Linked Polyethylene Cable Insulation
IEEE Transactions on Electrical Insulation, 1983The techniques of etching by carbon tetrachloride vapor and by permanganic acid are shown to be prone to artifacts, and so earlier conclusions based on these techniques, i.e. that XLPE cable insulation has a large scale (>> 10 ?m) spherulitic texture structure, need to be reexamined. A comparison with XLPE film samples, where spherulite size is readily

Space charge behavior of chemically cross-linked and radiation cross-linked polyethylene
2000 Annual Report Conference on Electrical Insulation and Dielectric Phenomena (Cat. No.00CH37132), 2002This paper presents results of an investigation having the aim to compare electrical and oxidative performances of chemically and radiation cross-linked polyethylene. Gamma irradiated and peroxide crosslinked specimens are characterized through dc space charge observations, as well as ac electric strength and oxidation induction time measurements ...

The effect of cross-linking and cross-linking agent by-products on tree growth in polyethylene
Conference on Electrical Insulation & Dielectric Phenomena - Annual Report 1976, 1976This paper summarizes a study of the effect of cross-linking processes and by-products of cross-linking on electrochemical tree growth in polyethylene insulated cables. The investigations dealt with cables cross-linked by radiation and chemically by peroxides.

Highly Cross-Linked Polyethylene The Debate Is Over—In Opposition
The Journal of Arthroplasty, 2005Highly cross-linked polyethylene compared to conventional ultra high molecular weight polyethylene (UHMWPE) results in significantly decreased wear in hip simulators and early prospective randomized clinical studies. However, the contact stresses in a total knee bearing surface are much higher than in a total hip.

Uphill Diffusion of Antioxidant in Cross-Linked Polyethylene
2018 IEEE Conference on Electrical Insulation and Dielectric Phenomena (CEIDP), 2018Cross-linked polyethylene (XLPE or PEX) is a major material for cable insulation. Antioxidants are usually added to XLPE to prevent the insulation from oxidation. However, antioxidants diffuse out of an XLPE matrix during thermal ageing, which accelerates oxidation, causing the degradation of the insulation.

Micro-Indentation Test of Cross-Linking Polyethylene
Advanced Materials Research, 2015Radiation crosslinking of linear polyethylene (LLDPE) is a well-recognized modification of improving basic material characteristics. This research paper deals with the utilization of electron beam irradiated LLDPE on the micro-indentation test. The effect of the irradiation on mechanical behavior of the tested polyethylene was investigated. The results

Conventional and Cross-Linked Polyethylene Properties
2005Highly cross-linked ultra high-molecular-weight polyethylene has shown great promise as an orthopedic bearing in total hip replacements. However, the enhanced resistance to plastic deformation that benefits wear behavior comes at the expense of other mechanical properties.

Cross-linked polyethylene: why the enthusiasm?
Instructional course lectures, 2001If these materials behave in vivo as they do in vitro and if no unexpected complications occur, periprosthetic osteolysis should be reduced, the duration of THR success should be greater, and the percentage of complications should be lower. Femoral loosening, socket loosening, and pelvic and femoral lysis should be reduced.
