China 2-Mercaptobenzimidazole/2-Benzimidazolethiol Rubber
The dosage in latex foam rubber is 0.5 parts. Because this crystal has a bitter taste, it is not suitable for use in food contact rubber products. Used as a sensitive reagent and rubber accelerator for testing gold, bismuth, cadmium, cobalt, mercury, nickel, lead, thallium and zinc. product pictures:

- 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 mechanical properties of vulcanizates?
- Vulcanizates have moderate mechanical properties. When a combination of ZnO – 5 phr + MgO – 4 phr is used, the cross linking effect is stronger and the scorch safety is within acceptable limits. Only Calcined and extra light MgO is used for high activity and is generally added first in the mixing cycle.
- 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 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.
- 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.
- Is vulcanizate a polysulfidic cross link?
- The combined sulfur with rubber exists predominantly in the ‘Polysulfidic cross links’ form and the amount of free sulfur and the ratio of free sulfur to accelerator varies from rubber to rubber. A fair degree of wasted sulphides and main chain modifications are present in the vulcanizate.
