Effects of Sulfur Accelerators on the Performance of EPDM
Understanding the role played by accelerators in the vulcanization of elastomer blends is further compli-cated by differences in their solubi-lities in the elastomers which make-up the blend. In this study, blend properties were optimized by se-lecting accelerators with a shorter scorch time and a faster cure rate in the EPDM phase than in the SBR phase.

ELASTOMERE UND KUNSTSTOFFE ELASTOMERS AND PLASTICS Effects
EPDM phase strongly depends on the solubility of accelerator in the elastomers. The purpose of this study is to deter-mine the role played by accelerators in the vulcanization of EPDM/SBR blends. Effects of the accelerators in final com-pound properties including: mechanical properties, ozone resistance, heat aging, and compression set are presented.

Sulfur Vulcanization
The cross-linking reaction between sulfur and rubber occurs mainly at the carbon-carbon double bonds (C=C) in large excess of sulfur. Often accelerators are added to speed up the vulcanization and to reduce the amount of free sulfur which has a detrimental effect on the properties of the cured rubber.
