Abstract: The invention relates to a composite comprising a thermosetting resin with a hardness of at least 55 Shore D, wherein the resin essentially consists of an ethylene ?-olefin copolymer with a density of less than 880 kg/m3, which resin is crosslinked to a degree such that the volume swelling measured in decaline after 64 hours at 23° C. is less than 50% by volume on the composite and the composite contains at least 40% by volume of a reinforcing filler, wherein the vol % of the filler is related to the volume of the resin. The composite according to the invention is an excellent isolator when at least 100 phr cork are present in the composite. A composite according to the invention can be made by crosslinking of the copolymer in the presence of a high amount of peroxide in the presence of at least 40% by volume on the resin of a filler.
