- 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 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 a vulcanization system?
- A vulcanization system not requiring free or donated sulfur. (These are based on metal oxides, organic peroxides etc.) Para Benzoquinonedioxime and dibenzoyl quinine dioxime can cure many rubbers through their free radical reactions.
- 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.
