Epoxy/Silicone Rubber Blends for Voltage Insulators and Capacitors Applications

In this research the epoxy/silicon rubber blends were prepared by adding the silicone rubber with varying weight (0.0, 0.25, 0.5, 0.75 and 1gm) to epoxy resin. Some thermal properties are determined for different samples of blends. The bulk resistivity and dielectric constant were evaluated and related to the neat epoxy. The results suggest that the inclusion of silicone epoxy effectively improved in the glass transition temperature (Tg) and the thermal insulation also improved the electrical properties like resistance and dielectric constant for using it as capacitor at high frequencies and in the high voltage strength applications.
