Accelerators are the substances that accelerate the vulcanization and make positive contributions to the properties of the products. They create different chemical effects during the vulcanization because of having different chemical structures.
The basic effects of the organic accelerators are following:
When used with sulfide, they accelerate the crossed bounding reaction. Therefore, it’s formed short and economic cooking durations. The product gets more resistant to ageing.
When two or more accelerators are used together, they create an effect that enforces them. By adjusting their utilization rates with different accelerator combinations, there can be provided very good properties concerning vulcanization beginning and continuation.
