Thermal degradation of UHMWPE

Journal of Thermal Analysis, 1997
The thermal behaviour of ultra-high molecular weight polyethylene (UHMWPE) of different molecular weights was examined by thermal analysis methods. The melting temperatureTm and the heat of melting δH were measured by the DSC method. The thermooxidative degradation process was investigated by using a MOM Q-1500 D derivatograph at various heating rates ...

Statistical wear analysis of PA-6/UHMWPE alloy, UHMWPE and PA-6

Wear, 2001
This paper, based on an orthogonal experimental design and analysis method, reports the wear of a blend of polyamide-6/ultrahigh molecular weight polyethylene (PA-6/UHMWPE), using a pin-on-disc test, and rubbing against a stainless steel counterface. The wear behavior of PA-6 and UHMWPE was also investigated for the purpose of comparison.

Dispersion of Pristine Cnt in Uhmwpe Solution to Prepare Cnt/Uhmwpe Composite Fiber

Polymers and Polymer Composites, 2014
CNT dispersion in polymer matrices uniformly remains a challenge. Uniform dispersion of carbon nanotube (CNT) within ultra-high molecular polyethylene (UHMWPE) solution is the first step to achieve CNT/UHMWPE fibers with excellent properties. Several approaches have been tried.

Nanotribological Properties of UHMWPE/Quartz Composites

Materials Science Forum, 2005
Wear of ultra-high molecular weight polyethylene (UHMWPE) and its composites is one of the main obstacles that limit the longevity of total joint replacements. Compression molded UHMWPE/quartz composites with organosiloxane as a cross-linking agent for UHMWPE matrix, were tested in nanoindentation and nanowear.

Wettability of nano-epoxies to UHMWPE fibers

Journal of Colloid and Interface Science, 2006
Ultra high molecular weight polyethylene (UHMWPE) fibers have a unique combination of outstanding mechanical, physical, and chemical properties. However, as reinforcements for manufacturing high performance composite materials, UHMWPE fibers have poor wettability with most polymers.

In vivo UHMWPE biodegradation of retrieved prosthesis

Biomaterials, 1998
Sixty-two ultra high molecular weight polyethylene prosthetic components (PEs) (31 tibial plateaux and 31 cups), sterilised by gamma rays or ethylene oxide (EtO), were retrieved after 1-12 years depending on different medical reasons and were studied by FTIR spectroscopy with derivatisation of oxidised species.

Oxidation in Prosthetic UHMWPE

2019
In this chapter, we will consider the oxidation process involved in high-energy radiation sterilization of UHMWPE, as generally used in the field of orthopedics. The macroradicals produced during irradiation, their stability in various morphological phases, and their reactivity with chain imperfections, as well as the effect of oxygen and additives in ...
