Vulcanization is a crucial process in the rubber industry as it imparts desirable properties to rubber, such as improved strength, elasticity, and resistance to heat and chemicals. It involves the cross-linking of polymer chains using sulfur or other curing agents, resulting in a three-dimensional network structure. However, deviations from the optimal vulcanization conditions can lead to undervulcanization or overvulcanization, affecting the final product’s performance.
