What is the best adhesive for bonding rubber?

2025-02-20

Rubber adhesives play a crucial role in various industries. Whether it is firmly connecting rubber components to metal, plastic, or other rubber components to form functional components, rubber bonding is essential.For example, in the automotive industry, rubber adhesives are crucial for manufacturing seals, gaskets, and shock absorbers. In industrial machinery, it ensures the durability of rollers and belts. Medical devices rely on adhesive rubber to manufacture flexible tubes or protective covers. Rubber adhesives are also commonly used in consumer goods such as footwear and electronics, as their durability and functionality are crucial. Whenever a product requires strength, flexibility, or environmental resistance, rubber bonding becomes a critical step in the manufacturing process. Why is rubber type crucial for bonding?Each type of rubber material has different characteristics, such as flexibility, chemical resistance, and surface energy, which can affect its compatibility with adhesivesLow surface energy: such as silicone and EPDM rubber, require the use of primer or specialized adhesive to ensure firm bonding.Plasticizer migration: Rubber such as NBR, SBR, EPDM, etc. may release plasticizers over time, affecting long-term adhesion performance.Environmental conditions: Some rubbers perform well in extreme temperatures or harsh environments, requiring adhesives to work under these conditions.Surface treatment of rubber bondingProper surface treatment is crucial to ensure the firmness of rubber bonding. Rubber surfaces often adhere to contaminants such as release agents, slip additives, or lubricants, which can affect adhesion.Cleaning the surface with solvents such as isopropanol can effectively remove these impurities, but it is important to avoid using corrosive solvents such as acetone, which may damage certain rubber.To improve adhesion, surface energy can be increased by polishing the rubber surface or using plasma, chemical primer, and other methods, especially for low surface energy rubber such as silicone and EPDM.Due to the migration of plasticizers in certain rubbers over time, it is…
