Abstract
A silicone rubber laminate including a conductive layer of cured silicone rubber containing carbon black and a dielectric layer of cured silicone rubber stacked and integrated to each other. The bonding force is enhanced by applying to the conductive layer a dielectric uncured silicone rubber composition comprising (a) an organopolysiloxane containing at least two alkenyl groups per molecule, (b) an organopolysiloxane containing at least two SiH groups per molecule, (c) reinforcing silica, (d) an organic silicon compound having an alkenyl group per molecule, and (e) a platinum catalyst, the molar ratio of the SiH group in component (b) to the total alkenyl group in components (a) and (d) ranging from 1:1 to 4:1, and curing the composition.
