Abstract

Conventional thermoplastics are widely used as insulating materials in various industrial fields, but various research efforts are being conducted to improve their thermal stability and flame retardancy. In this study, poly(ethylene-co-vinyl acetate) (EVA)/high-density polyethylene (HDPE)/intumescent flame retardants (IFRs) blends were prepared, and changes in properties were investigated according to the IFRs contents and electron beam irradiation conditions. As the content of IFRs increased, the flame retardancy of the blends improved significantly, but mechanical properties deteriorated. Mechanical properties, thermal stability, and flame retardancy were enhanced by electron beam irradiation, attributed to the formation of crosslinked network structures. UL-94 vertical tests results revealed that blends containing more than 50 g of IFRs and irradiated at 100 kGy exhibited a UL-94 V-0 rating. Therefore, the EVA/HDPE/IFRs blends prepared in this study can be applied as insulating materials with excellent thermal stability, mechanical properties, and flame retardancy.

期刊介绍： Radiation Physics and Chemistry is a multidisciplinary journal that provides a medium for publication of substantial and original papers, reviews, and short communications which focus on research and developments involving ionizing radiation in radiation physics, radiation chemistry and radiation processing. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. This could include papers that are very similar to previous publications, only with changed target substrates, employed materials, analyzed sites and experimental methods, report results without presenting new insights and/or hypothesis testing, or do not focus on the radiation effects.
