Dielectric Study at Microwave Frequencies of Water-treed Crosslinked Polyethylene
The dielectric properties of water-treed crosslinked polyethylene (XLPE) were studied by using a hollow microwave waveguide system between 135 MHz and 13.6 GH5. The dielectric loss of water-treed XLPE is proportional to water content. Water-treed XLPE has a low relaxation frequency which is probably due to bound water. The binding of water in trees was confirmed by the lower apparent water diff...
متن کاملWear of highly crosslinked polyethylene acetabular components
BACKGROUND AND PURPOSE Wear rates of highly crosslinked polyethylene (XLPE) acetabular components have varied considerably between different published studies. This variation is in part due to the different techniques used to measure wear and to the errors inherent in measuring the relatively low amounts of wear in XLPE bearings. We undertook a scoping review of studies that have examined the i...
متن کاملA ruthenium catalyst yielding crosslinked polyethylene.
A ruthenium phosphane aryl sulfonate was found to be an efficient catalyst for the polymerization of ethene. Surprisingly, the resulting polyethylene is crosslinked.
متن کاملZirconia and alumina ceramics in comparison with stainless-steel heads. Polyethylene wear after a minimum ten-year follow-up.
Although alumina has been used in orthopaedic surgery since the 1970s, the long-term clinical results of zirconia have not been well documented in vivo. We studied hips with these two different ceramics during the same period and with a minimum follow-up of ten years. Because the size of the alumina and zirconia heads was different, hips with 32 mm alumina heads and those with 28 mm zirconia he...
