Storing Effects on Electrical Properties of High Energy Electron Beam Irradiated LDPE and HDPE

Abstract

In this work, the effect of storing time on the variation of surface and volume resistance of the 10 MeV electron beam irradiated LDPE and HDPE samples was investigated. This study was carried out about one month after irradiation. The samples were prepared in sheet form with thickness of 2 AE 0.1 mm and irradiated at the doses of 70 to 370 kGy. All the samples were kept at room temperature. The results show a peak at about 25 days after irradiation in surface resistance for all the samples. The volume resistance measurements did not show any significant variation.

Electron beam cross-linking of EVA/TPU blends

“…EVA copolymer grade 8430 containing 18% vinyl acetate with a MFI of 2 g/10 min, density of 0?93 g cm 23 and shore hardness of 92 D was obtained from Hundai (Korea). TPU; Desmopane grade DP 1490 A with shore hardness of 90-94 A and a density of 1?206 g cm 23 was supplied by Bayer AG (Germany).…”

“…High energy EB cross-linking of polymers [20][21][22][23] offers some significant advantages over the chemical methods, e.g. no restriction on the temperature limit in extrusion processing, no residual peroxide or unwanted byproducts, high cross-linking rate, low energy consumption and saving in space for equipment required to carry out cross-link process.…”

The Optical and Chemical Response of Thermal Neutron-Irradiated CR-39 Polymeric Track Detector after Annealing

“…This process of eliminating the above-mentioned effect is called annealing. Radiation effects induced by ionizing particles such as electrons, ions and photons have been largely favored to modify the chemical and physical properties of polymers in recent years [1][2][3][4][5][6][7][8][9][10] .…”
