METHOD FOR MOLDING AND VULCANIZING RUBBER PRODUCT

摘要

PURPOSE:To mold and vulcanize a rubber product such as a tire with good workability without generating molding inferiority by using vulcanizing bladder excellent in mechanical properties, physical properties such as hot water resistance and chemical properties and having good durability and releasability. CONSTITUTION:In the molding and vulcanization of a rubber product using a vulcanizing bladder, the vulcanizing bladder is formed so as to have a multilayered structure composed of a plurality of layers and has a layer (A) composed of a rubber composition based on org. rubber on the innermost side thereof and a layer (B) composed of a rubber composition whose release stress with the rubber product is 0.5kg/cm or less on the outermost side thereof.
