selection of ultra/secondary accelerators in combination with a delayed action accelerator (e.g. sulfenamide) will allow sufficient scorch delay before the onset of vulcanization and high torque after the start of vulcanization. one must select ultra/secondary accelerators that work in a synergistic manner with other ingredients in a compound.

- What role does accelerator play in vulcanized rubber processing?
- In general, the accelerator plays an important role in rubber processing, especially the vulcanization step. Accelerators could increase the reaction rate between rubber and sulfur and permit the vulcanization with greater efficiency. Many researchers have also studied the influence of different accelerator types on vulcanized rubber properties.
- Why do guanidine derivatives vulcanize?
- This phenomenon was due to the chemical nature of used accelerators. DPG accelerator (guanidine derivatives) is characterized by medium activity and it is usually used with other accelerators. TBBS, CBS and MBT accelerated systems provide two functions during vulcanization of rubber compounds.
- What is sulfur vulcanization?
- Vulcanization is the conversion of a high-molecular mate-rial from the plastic to the elastic state. One of the key chemical reactions in this process is that of rubber with sulfur. Sulfur vulcanization, widely used in the rubber industry, requires the use of vulcanization accelerators such as Vulkacit®.
- Does vulcanizing system type affect curing properties?
- The effect of vulcanizing system type on curing characteristics, static mechanical properties (tensile strength, elongation-at-break, hardness and resilience), dynamic mechanical properties and thermal properties of reclaimed ground tire rubber was investigated.
