Effects of accelerators on the cure characteristics and

Diphenylguanidine (DPG) is most frequently used as a secondary accelerator to synergise with thiazole accelerators. As secondary accelerator, DPG in combination with MBTS contributes to a powerful cure activation effect that imparts high modulus, tensile strength, dynamic and aging properties of rubbers.

Thus, the science of accelerators and retarders was born. An accelerator speeds up the cure reaction, while a retarder delays it. A typical retarder is cyclohexylthiophthalimide. In the subsequent century chemists developed other accelerators and ultra-accelerators, which are used in the manufacture of most modern rubber goods. References

Vulcanization. Vulcanization is a chemical process, invented by Charles Goodyear, used to harden rubber. Vulcanization traditionally referred to the treatment of natural rubber with sulfur and this remains the most common example, however the term has also grown to include the hardening of other rubbers via various means.
