  • What is a deovulc vulcanization chemical?
  • The range of Deovulc vulcanization chemicals includes balanced accelerator mixtures and single accelerator preparations, activators, stabilizers, retarders and sulfur preparations. Depending on the application, conventional or nitro-samine-free cross-linking can be realized. Combination of thiazoles, dithiophosphates and alkaline accelerators.
  • What is accelerated sulfur vulcanization?
  • The first step in accelerated sulfur vulcanization is the formation of ‘Accelerator-polysulfide’ by reaction of Accelerator + Zinc Oxide + Stearic acid + Sulfur. In the absence of Zinc Oxide molecule of the Type A is formed. The organic pendent group in this Type A molecule is Benzothiazole.
  • 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.
  • How do I select a vulcanizing accelerator?
  • The selection of an accelerator will depend on the specific vulcanizing system and curing properties. Explore the classification of accelerators, the checklist to select the right accelerator based on the specific vulcanizing systems and curing properties.
