Natural rubber, alongside steel, coal, and petroleum, is regarded as one of the world’s four major industrial raw materials and serves as an irreplaceable strategic commodity in sectors such as transportation, healthcare, and national defense. However, China, the world’s largest consumer and importer of natural rubber, is projected to import 6.492 million tons by 2025, with an external dependence exceeding 80% and a self-sufficiency rate of less than 25%.

Vulcanized bonding between rubber and metal is a complex yet critical technology, widely employed in industries such as automotive, aerospace, machinery, and medical devices. Through the vulcanization process, rubber and metal can be firmly joined, combining their respective advantages—such as rubber’s elasticity and vibration‑damping properties with metal’s high strength and rigidity—thereby enhancing the material’s overall performance. This paper provides an in-depth examination of rubber–metal vulcanized bonding, covering its underlying principles, methods, applications, and associated challenges.

Why does rubber–metal bonding fail?
Jun 29,2026
The bonding of rubber to metal has a long history. Common methods include direct bonding, hard‑rubber bonding, brass‑plating, and adhesive bonding; among these, adhesive bonding is currently one of the most widely used and effective approaches. This paper examines the underlying bonding mechanisms and processing techniques, analyzes the various factors that can lead to failure in vulcanized rubber–metal adhesion, and proposes corresponding mitigation strategies.
