    Vulcanization. Vulcanization is a chemical process in which the rubber is heated with sulphur, accelerator and activator at 140–160°C. The process involves the formation of cross-links between long rubber molecules so as to achieve improved elasticity, resilience, tensile strength, viscosity, hardness and weather resistance.

    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.
