A vulcanization accelerator is typically used in combination with sulfur as the cross-linker, and with zinc oxide and stearic acid as activators. Other additives can be added too, but for the cross-linking reaction the abovementioned ones are the most important. The various types of rubber used in the various tire compounds all have different
Vulcanization Accelerators
Vulcanization Accelerator. is a compound that increases the speed of vulcanization and that enables vulcanization to proceed at lower temperature and with greater efficiency. Vulcanization accelerators can be classified as primary and secondary accelerators. Important primary accelerators include thiazoles and sulfenamides.

Vulcanization & Accelerators. Thiuram class includes accelerators such as TMTM, TMTD, TETD, TBzTD and DPTT. Thiurams are ultra-fast accelerators for NR, SBR, BR, NBR and other highly unsaturated rubbers and themost preferred primary accelerator for sulfur cured low-unsaturation content rubbers like butyl (IIR) and EPDM.

- 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.
- What are vulcanization accelerators?
- Vulcanization accelerator also decreases the amount of sulfur needed to cross-link the polydiene, which improves the aging properties of the vulcanized rubber. The vulcanization accelerators can be further classified as primary and secondary accelerators. Some representative examples of primary accelerators include thiazoles and sulfenamides.
- 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).
- 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.
- What is vulcanization process?
- Vulcanization is a cross linking process in which individual molecules of rubber (polymer) are converted into a three dimensional network of interconnected (polymer) chains through chemical cross links(of sulfur).
- Which type of cure is used in vulcanization process?
- This type of cure is mainly used for butyl rubber (IIR) where sulfur cures are undesirable (too slow or sulfur presence is objectionable). Combination of CDO/Dibenzo-CDO with ZnO, MBTS, Lead oxide can produce faster cure rates in IIR which can be suitable for continuous vulcanization process (e.g. cables).
