The materials employed in the electrical insulation of cables/wires used in the automotive industry are exposed to several external factors that may affect the overall performance of the system. These factors include mechanical vibrations, high temperature, humidity, wind and rain. In order to have a stable and trustworthy solution, these materials need to follow specific criteria in what regards their abrasion, thermal and chemical resistance, flame retardancy, and mechanical properties. In this work, new crosslinked polyethylene (XLPE) compounds were developed by means of compound extrusion, using peroxide crosslinking, and also different polymeric matrices. Ultimately, blends of ethylene-vinyl-acetate (EVA) and low density polyethylene (LDPE) with alumina trihydrate (ATH) and magnesium hydroxide (MH), exhibited a significant increase in both the oxidation-induction time -higher than 95 min (OIT), and abrasion resistance (sandpaper abrasion) -approximately 38.1 g, while maintaining a low density profile and fair mechanical properties, when compared with the selected standard material, based on a ATH-additivated EVA material. These findings show that such material can be considered as a promising and suitable candidate for high performance cables.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
