Vulcanization & Accelerators
Vulcanization & Accelerators Vulcanization is a cross linking process in which individual molecules of rubber (polymer) are converted into a three dimensional network of interconnected (polymer) chains through chemical cross links(of sulfur). The vulcanization process was discovered in 1839 and the individuals responsible for this discovery were

Effects of accelerators on the cure characteristics
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 [5]. In MBTS acceleration systems,
