Alkylphenol disulfide is widely used as a vulcanizing agent in the rubber industry, particularly for improving the cross-linking efficiency during the vulcanization process. It enhances the mechanical properties of rubber, such as tensile strength, elasticity, and resistance to wear and tear, making it suitable for manufacturing tires, seals, and gaskets. Additionally, it acts as a plasticizer and processing aid, facilitating smoother production processes. In lubricants, it serves as an extreme pressure additive, reducing friction and preventing wear in high-stress machinery applications. Its antioxidant properties also contribute to extending the lifespan of rubber and lubricant products by inhibiting degradation caused by heat and oxidation.
