inc oxide is essential in the rubber industry due to its critical role in vulcanization, enhancing the quality and durability of rubber products. It activates the curing system by forming zinc soap with stearic acid, creating a powerful vulcanizing agent when combined with sulfur. Additionally, zinc oxide improves cross-linking density by stabilizing sulfur bonds, resulting in stronger and more reliable rubber structures. It also boosts anti-aging properties by neutralizing harmful by-products like H2S, thereby extending the lifespan and performance of rubber products. This makes zinc oxide indispensable for safer, longer-lasting rubber applications.
