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.
