An electrically conductive silicone rubber composition having a positive, non-linear, temperature coefficient of resistance and which is substantially non-conductive at a temperature above a predetermined transition temperature, the composition comprising up to 25% based on total material weight of conducting carbon black, from 29% to 62% based on total material weight of at least one additive having a particle size between 0.005 microns and 100 microns, being compatible with the rubber, and having a melting point above the curing temperature of the rubber.
