  • What type of rubber is used for vulcanization?
  • Since most of the research on devulcanization has been made on waste tires, this review mainly focuses on the most widely used rubber classes for this application, i.e., natural rubber (NR) and styrene-butadiene rubber (SBR), and the most common vulcanization technique, i.e., sulfur vulcanization.
  • Does ZDBC extra/Zix cure vulcanisation faster than ZDEC?
  • At temperatures 60 - 80 ̊C, ZDBC extra/ZIX combination showed faster rate of vulcanisation but at 100 ̊C, all were found to be similar excepting ZDEC, which did not show any effective cure even at 100 ̊C.
  • How is vulcanized rubber broken down?
  • In ambient grinding, the vulcanized rubber is broken down mechanically at room temperature. The mill type and the number of grinding steps determine the final size distribution of the rubber particles. This process is generally easy and inexpensive, but the price can become very high if a very fine mesh size is required.
  • Which vulcanized elastomers are safe?
  • t and heat stable vulcanizates in elastomers with low unsaturation. Additionally, Rhe-nocure-brand DR and Vulcuren brands will be presented as safer alternatives to 1, 3-diphenyl guanidine (DPG), which produc
