Investigating the Effect of Cross-Linking on the Shelf Life of SBR RubberCompounds Using the Principle of Time-Temperature Superposition

The properties of rubber compounds are greatly influenced by the duration of use due to theirmolecular characteristics. Operational temperature can hasten the process of molecular breakdown,leading to a shorter lifespan. Hence, strategies must be implemented to prolong the durability ofrubber compounds. One effective approach is the selection of an appropriate curing system duringthe formulation of the rubber mixture. In the present study, the longevity of three rubber compoundswith different curing systems—Conventional, Semi-Efficient, and Efficient—was studied using theconcept of temperature-time superposition. The findings suggest that the utilization of an efficient orsemi-efficient curing system formulation can significantly enhance both the service life and thermalresistance compared to the conventional system
