Claim 4:
5. The conductive liquid silicone rubber composition in accordance with claim 1, wherein the extra conductive carbon black (e)(i) has at least one of the following properties:
(i) a BET surface area of at least 500 m2/g, optionally of from 500 to 1,600 m2/g, optionally of from 500 to 1,500 m2/g, optionally of from 600 to 1,300 m2/g, optionally of from 750 to 1,250 m2/g, as determined by ASTM D 6556; and/or
(ii) a D50 aggregate particle size of between 5 to 500 nm, optionally of from 10 to 200 nm, as measured by using disc centrifuge photosedimentometry (DCP) according to ISO 15825:2017; and/or
(iii) a dibutyl phthalate (DBP) pore volume of from 300 to 600 ml/100 g, optionally of from 300 to 550 ml/100 g, optionally of from 300 to 400 ml/100 g, as measured using ASTM D-2414.
