“…Figure 6 shows the effect of EVA (40-100 phr) on the GC values of compounds (1J-8J). Increasing irradiation (0-110 kGy) generated high three-dimensional network inside polymer matrix [5] . Thus, the GC values increased sharply with the increase of irradiation at each EVA level.…”

“…Polyolefins have some disadvantages such as low mechanical properties as well as poor compatibility with fillers which deteriorate the mechanical properties of compounds [2][3][4] . The processability and the properties of the compounds, polyolefins=fillers, can be improved by adding lubricant and compatibilizer [5][6][7] . Specifically, polyolefins are nonpolar and incompatible with metal hydroxide fillers.…”

Electron beam irradiation efffects on polymer cross-linking used for wire and cable insulations are still being researched. This study showed that upon irradiation, ethylene vinyl acetate (EVA) and maleic anhydride grafted polyethylene (LDPE-g-MAH) addition as coupling agent to the LDPE/fillers, improved processing and mechanical properties of compounds at each irradiation dosage (0-110 kGy). A gradual increase in gel content (GC) and tensile strength (TS) with a concomitant decline in elongation at break (EB), hot set (HS) and densities of compounds were observed upon irradiation of the blends. Melt flow index test (MFI) results revealed that filler addition reduced compounds flowing and in consequence, caused difficult to process. The LDPE/EVA blends TS values decreased significantly with fillers addition (ATH, MH and ZB). Consequently, this study demonstrated that filler addition to irradiated low density polyethylene (LDPE) impaired processing and mechanical properties of compounds, whereas, LDPE-g-MAH (6-12 phr) and EVA (0-100 phr) addition to the compounds (1I-8I) improved the blends flowability and mechanical properties at each irradiation dose (0-110 kGy). Moreover, among additive fillers, MH content compounds presented the strongest adhesion forces with polymeric compounds compared with analog compounds content aluminum trihydrate (ATH) or zinc borate (ZB) at each irradiation dosage.

“…However, high energy radiation like electron beam can be used as an alternative to these methods. Because of its ability to produce crosslinked networks with a wide range of polymers, low operation cost, additive free technique and room temperature operations are among the added advantages of radiation vulcanization [6][7][8][9][10] .…”

“…The mechanical and thermomechanical properties of gamma irradiated PP/EVA blends were studied by Thomas et al [9] and Minkova and Nikolova [10]. Sharif et al [11] studied the effects of radiation on mechanical properties of LDPE/EVA. In this paper, we studied effect of 3 MeV proton irradiation on electrical properties of EVA films at different fluences.…”

MeV ions passing through polymeric films modify their electrical, optical and thermal properties and these changes are related to changes in the chemical structure of the polymers. Ethylene vinyl acetate (EVA) films were irradiated with 3 MeV proton beam at different fluences of 10 13 , 10 14 and 10 15 ions/cm 2 . AC electrical properties of pristine and irradiated samples were studied in the frequency range 100 Hz to 100 kHz by means of an LCR meter. There is an exponential increase in conductivity with log frequency and conductivity increases as fluence increases. The dielectric loss/constant is observed to change with the fluence. FTIR spectra reveals significant change in intensities of functional groups at a fluence of 10 15 ions/cm 2 due to scissioning of polymer chains.
