Abstract: Addition curing electrically conductive liquid silicone rubber (LSR) compositions, their methods of preparation, and cured elastomeric products made from the compositions are provided. The compositions are cured to form elastomeric products suitable for high voltage applications such as cable joints, cable terminal applications, cable accessories and connectors. In general, the composition comprises: (a) at least one polydiorganosiloxane having at least two alkenyl groups per molecule: (b) at least one organohydrogenpolysiloxane: (c) at least one reinforcing filler: (d) at least one hydrosilylation catalyst: and (e) an electrically conductive filler. Component (e) comprises: (i) extra conductive carbon black: and (ii) single walled carbon nanotubes.
