Accelerator choice is critical. Selecting a good accelerator system is difficult. Many parameters, such as raw rubber storage stability, processability, scorch, crosslinking, and cured rubber requirements to name a few, come into consideration. Primary accelerators such as DPL DPOCURE MBT and MBTS are the most popular accelerators and offer a good start. Their good qualities are the effective acceleration they provide at medium and high temperatures and their wide range of curing rates and scorching characteristics. They usually provide considerable scorch delay, medium to fast cure, and good modulus development.
