Abstract

Two polyethylene blends crystallized under non-isothermal conditions were compared to a crosslinked polyethylene (XLPE) reference material. One blend contained a gelation agent, which forms a network structure within the polymer host. Compared to the reference material, the blends offered higher melting points, increased electrical breakdown strength and enhanced thermo-mechanical stability at high temperatures. Dissipation of stored charge was improved in the blend containing the gelation agent. The provision of recyclable insulation capable of operating at higher temperatures than XLPE, combined with enhanced dielectric properties, may prove invaluable to cable manufacturers.
