Abstract
The mechanical properties of flame-retardant high-density polyethylene/ethylene vinyl-acetate copolymer/magnesium hydroxide (HDPE/EVA/Mg(OH)2) composites for cable materials are usually poor due to the high loading of the filler. In this study, high-energy electron beam irradiation was applied to HDPE/EVA/Mg(OH)2 composites in the presence of triallylisocyanurate, an irradiation sensitizer. The effects of high-energy electron beam irradiation on the properties of irradiated HDPE/EVA/Mg(OH)2 composites were investigated through the measurements of gel content, limiting oxygen index, tensile testing, thermogravimetric analysis, and scanning electron microscope. The results showed that the thermal, mechanical and flame-retardant properties of the HDPE/EVA/Mg(OH)2 composites were improved by using high-energy electron beam irradiation.
