- 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 is the role of accelerator in vulcanization?
- Accelerator also Decreases the Quantity of Sulphur necessary for vulcanization and thus improving 'aged' properties of the rubber vulcanizates. Accelerators are also classified as Primary and / or Secondary accelerators based on the role they play in a given compound.
- 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 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.
