Abstract: A method of lubricating an expandable rubber bladder is described for use during a vulcanization of a green tire within a metal press. The method can include applying compositions in the form of emulsions of silicone oils to the inner surface of the green tires and/or to the outer surface of the vulcanization bladders to facilitate the molding-demolding thereof during the manufacture of the tires.

Abstract: The present invention concerns novel polyorganosiloxane compositions that can be hot-vulcanised into silicone elastomers, i.e. that can be vulcanised at temperatures generally in the region of between 100° and 200° C. and, if necessary, up to 250° C. The invention also concerns the use of these compositions for the production of casings or primary insulators used to form electrical wires or cables protected against fire. The invention finally concerns the electrical wires or cables protected against fire that are produced using said compositions.
