characterization of the natural rubber vulcanizates obtained
zinc diethyldithiocarbamate (zdec) is one of the most commonly used accelerators in natural rubber latex technology because of the properties of the corresponding vulcanizates. many studies using this accelerator have shown the presence of carcinogenic nitrosamines and therefore its unsuitability for the production of some goods.

- 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 the factors affecting vulcanizate properties?
- The degree and type of cross links are most important factors for achieving the desired vulcanizate properties. The type of cross links depends on: Cure time. Generally, high Accelerator / Sulfur ratio and longer cure time increase the number of monosulfide cross link formation at the expense of polysulfide cross links.
- 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 is vulcanization chemistry?
- Vulcanization is the phenomenon of formation of cross links with rubber macromolecules. These cross links can be made up of sulfur atoms or they can have some other chemical composition if other cross linking agents are used.
