Abstract

We investigated the factors that influence dielectric properties such as the breakdown strength and conduction current of linear low-density polyethylene. Films with a lower melt-flow-rate show a higher dielectric strength. Furthermore, the catalyst used to polymerize the film affects the dielectric strength, although additives in the film scarcely affect its electrical properties. The effect of crosslinking on dielectric breakdown in linear low-density polyethylene was found to be similar to that in low-density polyethylene.
