Basically, the combination of curing agent, accelerators and sulfur is used as the sulfur curing system of the diene rubber. Also, the accelerator activators, such as zinc oxide or stearic acid, and retarders, are added to the system.
How to use such ingredients governs the control of both processability and physical properties of the rubber products. We explain how to satisfy the various requirements from rubber production by compounding curing agent, accelerators, activators and sulfur, especially for natural rubber compounds.
