Abstract
An electrically insulating material including a continuous phase of a thermoplastic polymer and an additional phase incorporated therein of a liquid or easily meltable dielectric in the form of a wholly or partly interpenetrating network, and where the weight ratio of the polymer to dielectric is between 95:5 and 25:75.
Claims27
An electrically insulating material comprising a thermoplastic polymer and a dielectric having a weight ratio of polymer to dielectric between 95:5 and 25:75, wherein the thermoplastic polymer forms a network of solid polymer filled with the dielectric, the dielectric being a liquid or a solid that melts or softens at a lower temperature than the thermoplastic polymer such that the dielectric acts as a mobile phase in the solid polymer network, said insulating material maintaining its dielectric properties when subjected to voltages greater than 5 kV.
