    Accelerant

    The use of accelerators and activators lowers the activation energy of vulcanization reaction to 80-125kJ/mole from 210kJ/mole which is necessary if we use sulfur alone. Accelerators and activators break sulfur chains. Accelerated sulfur vulcanization systems require only 5-15 sulfur atoms per cross-link as compared to 40-45 S atoms/crosslink for a non-accelerated sulfur vulcanization.
