Abstract

An electrically conductive composition containing a cross-linked organopolysiloxane and an electrically conductive lamp black in which the electrically conductive lamp black comprises from 15 to 60 percent by weight based on the weight of the organopolysiloxane of furnace black having a surface area of from 40 to 100 m.sup.2 /g and from 5 to 25 percent by weight of acetylene black based on the weight of the organopolysiloxane.
