LAMINATE BASED ON SILICONE RUBBER COMPOSITIONS
The invention relates to a laminate comprising a first layer and a second layer directly covering the first layer, the first layer being a layer of a silicone rubber composition comprising a micrometric silicone powder and a mixture of crosslinkable organopolysiloxanes, the second layer being a layer of a silicone rubber composition comprising a hydrophobic silica and a mixture of crosslinkable organopolysiloxanes, the first layer and the second layer being crosslinked. The laminate, in particular when it is used as a coating for the outer surface of an expandable bladder for a tyre curing mould, makes it possible to eliminate moulding defects on the inner liner of the tyre.
