  • 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 is a ZMBT accelerator?
  • ZMBT accelerator is a primary accelerator for NR, SR and their latices; used as a secondary accelerator in sulfur cured latex. *Moisture,% max. *Residue on 100 mesh sieve,% max. *Residue on 230 mesh sieve,% max. Technical Product Sheets and SDS sheets are available for each of the chemicals listed. To access please click on the links above.
  • How is rubber vulcanized?
  • Vulcanization of rubbers by sulfur alone is an extremely slow and inefficient process. The chemical reaction between sulfur and the Rubber Hydrocarbon occurs mainly at the C = C (double bonds) and each crosslink requires 40 to 55 sulphur atoms (in the absence of accelerator).
  • 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.
