The present disclosure relates to a filled silicone rubber materialincluding at least 20 wt % of alumina tri-hydrate as a fillerdispersed in SiRto below the percolation threshold. The ATH is a mixture of a first ATH powder and a second ATH powder. The particle size distribution of the first and second ATH powders are such that the dvalue of the second ATH powder is less than the dvalue of the first ATH powder. The disclosure also relates to an insulatormade from the filled SiR material, and to a use of the insulator in a high-voltage direct current application.
