  • What is a DCBS accelerator?
  • Accelerator DCBS is a delayed action sulfenamide accelerator for use in natural and synthetic rubbers. It is recommended for applications where exceptionally long flow times are required. DCBS is particularly suitable for rubber goods subjected to high dynamic stresses. It is a primary accelerator
  • What vulcanizing agent is used in rubber?
  • Elemental sulfur is the predominant vulcanizing agent for general-purpose rubbers. It is used in combination with one or more accelerators and an activator system comprising zinc oxide and a fatty acid (normally stearic acid). The most popular accelerators are delayed-action sulfenamides, thiazoles, thiuram sulfides, dithocarbamates and guanidines.
  • What vulcanization system is used for natural rubber?
  • Both discovered the use of Sulfur and White Lead as a vulcanization system for Natural Rubber. This discovery was a major technological breakthrough for the advancement of the world economy. Vulcanization of rubbers by sulfur alone is an extremely slow and inefficient process.
  • Which accelerator is used for vulcanization?
  • The basic accelerators such as Guanidines, Thiurams, and Dithiocarbamates etc are used as Secondary accelerators to activate the primary accelerators. The use of secondary accelerators increases the speed of vulcanization substantially but at the expense of scorch safety.
