    Accelerator compositions and rubber compounding composition

    An accelerator composition and a rubber compounding composition in which a rubber is blended with a combination of three accelerators and sulfur for curing the rubber while minimizing the formation of iridescent sheen. The combination of accelerators included a thiolated morpholine, a dithiocarbamate and a benzothiazole.

    Performance of binary accelerator system on natural rubber

    concentrations of accelerator give direct influence on scorch safety and curing time of a rubber compound. Scorch safety is related to the allowable heat history of a rubber compound during the consecutive process. Thus, the knowledge of the response of each class of accelerator becomes mandatory. Frequently, a
