Vulcanization bonding is a composite processing technology that firmly joins uncured rubber with dissimilar materials such as metals and resins, simultaneously with the vulcanization reaction of the rubber. In this process, extremely high adhesive strength and durability are achieved by simultaneously advancing the cross-linking reaction of the rubber and the chemical and physical bonding with the dissimilar material, facilitated by an adhesive. The main processing method is typically simultaneous vulcanization bonding, where an adhesive-coated substrate and uncured rubber are heated and pressurized in a mold, performing molding and bonding in a single step. It is indispensable as a highly reliable bonding technology in the manufacturing of products such as automotive anti-vibration rubber, sealing materials, rollers, and industrial machine parts, where high performance is required through the composite formation of rubber and other materials.
