Application
The different roles of Magnesia in rubbers
Depending on the polymer type, MgO can play different roles:
1. Acid scavenger.
2. Scorch controller (vulcanization retarder).
3. Vulcanization or curing agent.
4. Vulcanization accelerator activator.
5. Heat stabilizer.
6. Acid neutralizer.
7. Color stabilizer.
8. Thickening agent.
9. Rheology modifier.
