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 vulcanizationand thus improving 'aged'
Mercaptobenzothiazole Wikipedia
Mercaptobenzothiazole. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). 2-Mercaptobenzothiazole is an organosulfur compound with the formula C6H4(NH)SC=S. It is used in the sulfur vulcanization of rubber.

Vulcanization an overview ScienceDirect Topics
Vulcanization, thus, is a process of chemically producing network junctures by the insertion of crosslinks between polymer chains. A crosslink may be a group of sulfur atoms in a short chain, a single sulfur atom, a carbon-to-carbon bond, a polyvalent organic radical, an ionic cluster, or a polyvalent metal ion.

- What is ZMBT & accelerator?
- In dry rubber applications, the performance of Wellt ZMBT is almost similar to Wellt MBT with slight scorch improvement. (%) max. (%) max. ZMBT & Accelerator ZMBT finds its main application in latex where it is used as a primary accelerator in combination with Wellt ZDMC or Wellt ZDEC.
- What is ZMBT (MZ)?
- ZMBT (MZ) is used for NR, IR, SBR, NBR, EPDM and latex. It is a secondary accelerator in combination with PZ and EZ. Similar performance as MBT at curing temperature in dry rubber application. Suitable for mold curing. Requires zinc oxide and stearic acid as activators in many kinds of rubber batches.
- What is wellt ZMBT used for?
- In dry rubber applications, the performance of Wellt ZMBT is almost similar to Wellt MBT with slight scorch improvement. Wellt ZMBT finds its main application in latex where it is used as a primary accelerator in combination with Wellt ZDMC or Wellt ZDEC. Latex films cured with Wellt ZMBT have a markedly higher modulus.
- What is a rubber accelerator?
- Rubber accelerators are substances that increase the speed of vulcanization, a process where rubber becomes more durable through the addition of sulfur at high temperatures. They play a pivotal role in reducing the curing time and improving the efficiency of the vulcanization process.
- What are the different types of rubber accelerators?
- There are several types of rubber accelerators, classified based on their composition and the type of rubber they’re used with. The most common ones include Thiazoles (MBT, MBTS, and ZMBT), Sulfenamides (CBS, TBBS, NOBS, etc.), Guanidines (D, DOTG), Thiurams (TMTM, TMTD, DPTT), and Dithiocarbamates (ZDEC, ZDBC, ZDMC).
- Are there alternatives to rubber accelerators?
- For individuals who have an allergic reaction to rubber accelerators, alternatives include using products made from synthetic rubber or rubber products that are free of accelerators. It’s also possible to use products made with alternative accelerators that don’t cause an allergic reaction in the individual.
