Abstract
An insulating composition having a polymer resin, a nanoclay, and one or more nanofillers. The insulating composition has a thermal conductivity of greater than about 0.8 W/mK, a dielectric constant of less than about 5, a dissipation factor of less than about 3%, and a breakdown strength of greater than about 1,000 V/mil. The insulating composition has an endurance life of at least 400 hours at 310 volts per mil.
