Abstract

PURPOSE:To obtain a green tire forming bladder of improved mold releasing, property, life etc., by covering its surface entirely or partially with silicone rubber. CONSTITUTION:Silicone rubber 2 is covered on the entirety or a part of the surface of a green tire forming bladder body 1. Self-adhering silicone rubber which adheres firmly to the surface of the bladder is preferable as the silicone rubber, and silicone rubber is made low viscosity with organic solvent of trichlorethylene, xylene etc. according to an application purpose and coated on the surface of the bladder by spray or a brush, a spatula etc.
