  • What is accelerator in rubber vulcanization?
  • An accelerator is defined as the chemical added into a rubber compound to increase the speed of vulcanization and to permit vulcanization to proceed at lower temperature and with greater efficiency. Accelerator also Decreases the Quantity of Sulphur necessary for vulcanization and thus improving 'aged' properties of the rubber vulcanizates.
  • Why do vulcanized rubbers need multiple accelerators?
  • Accelerator Combination: Each accelerator has unique properties that affect the vulcanization process. The simultaneous use of multiple accelerators is often necessary to achieve the desired processability and excellent physical and chemical properties of the vulcanized rubber.
  • Why is dispersibility important in rubber vulcanization?
  • Dispersibility: The dispersibility of an accelerator in a rubber compound is crucial for efficient mixing and uniform vulcanization. Poorly dispersible accelerators increase mixing time and power consumption, leading to uneven vulcanization.
  • Why should you choose a vulcanization accelerator?
  • This results in a faster vulcanization reaction rate, shorter vulcanization times, lower reaction temperatures, and a reduction in the amount of vulcanizing agent required. When selecting a vulcanization accelerator, it's important to consider several factors to ensure optimal performance and quality of the rubber compound.
  • How does vulcanized rubber aging affect performance & aging properties?
  • Counterfeit or substandard accelerators can negatively impact the performance and aging properties of vulcanized rubber. Scorching Performance: Scorching time is a critical parameter in the rubber manufacturing process. It is the interval during which the rubber material remains processable before the onset of vulcanization.
  • What vulcanization curve should a rubber accelerator have?
  • Vulcanization Flatness: The accelerator should have a broad vulcanization flatness curve during the optimal vulcanization period. This is particularly important for thick and solid rubber products to ensure even vulcanization and prevent defects.
