  • What are the different types of rubber vulcanizing accelerators?
  • W. He, In rubber tire production, three popular types of rubber vulcanizing accelerators exist that are similar in appearance (i.e., 2-mercaptobenzothiazole, 4,4′-dithiodimorpholine, and tetramethyl thiuram monosulfide).
  • Are vulcanization accelerators used as reclaiming/devulcanization agents?
  • Vulcanization accelerators are applied as reclaiming/devulcanization agents, as they have effect on the process of breakdown of cross-links and on secondary vulcanization of resulting reclaimed rubber [16, 17].
  • How does scorch time affect vulcanization of rubber compounds?
  • Increase of the scorch time enabled safer processing of rubber compounds. Optimum vulcanization time (t 90) and cure rate index (CRI) of investigated materials significantly depended on the type of accelerator and the ratio of accelerator to sulfur.
  • How can vulcanization improve rubber properties?
  • One of the simplest and economically beneficial methods of the enhancement of rubber properties is proper selection of curing system and conditions of vulcanization. These conditions significantly affect the cross-link density of vulcanizates, which to a large degree controls their mechanical and thermal properties [4, 5].
  • Are vulcanization accelerators safe?
  • Vulcanization accelerators (VAs) serve as crucial additives in synthetic rubber on a global scale. Despite their widespread use, the environmental presence, distribution, and associated exposure risks of VAs remain poorly understood.
  • Does vulcanizing system type affect curing properties?
  • The effect of vulcanizing system type on curing characteristics, static mechanical properties (tensile strength, elongation-at-break, hardness and resilience), dynamic mechanical properties and thermal properties of reclaimed ground tire rubber was investigated.
