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.

Abstract: A liquid curable silicone elastomer composition is disclosed. The composition comprises: an organopolysiloxane (A) comprising: an organopolysiloxane (A1) containing at least 2 alkenyl groups bonded to silicon atom per molecule and having a total alkenyl content of from 0.01 to 1.5 mmol/g, and an organopolysiloxane (A2) containing at least 2 alkenyl groups bonded to silicon atom per molecule and having a total alkenyl content of from 5.0 to 15.0 mmol/g; an organopolysiloxane (B) comprising an organopolysiloxane (B1) containing at least 2 silicon-bonded hydrogen atoms per molecule provided by siloxy units of the type (R2HSiO1/2)x where R is independently selected from hydrogen, an aliphatic a hydrocarbyl, an aromatic hydrocarbyl, or an organyl group and x≥2; a platinum based catalyst (C); an inhibitor (D) selected from the group consisting of acetylenic alcohols and their derivatives; and a silica filler (E).
