Abstract
Electric insulators are prepared from a mixture of a curable carrier reaction resin, a hardener for the carrier reaction resin and a filler which is a ground, hardened filler reaction resin. The insulators are advantageously used in electric devices containing an electronegative gas.
Claims3
An electric insulator adapted for use in the interior of an encapsulated electric device in which electric discharges or arcs or both occur at least at times and which is filled with an electronegative gas, said insulator comprising the polymerization hardened product of a mixture consisting essentially of a polymerization hardenable cycloaliphatic epoxy resin, a hexahydrophthalic acid anhydride hardener and a filler, wherein said filler is a finely divided, ground, cured bisphenol A epoxy resin in an amount up to 150 parts per 100 parts of said cycloaliphatic epoxy resin.
