Role of Zinc Oxide in Rubber Compounding
Zinc Oxide plays a critical chemical role in rubber vulcanization by activating accelerators and facilitating crosslink formation.
Key Functions:
- Activates sulfur-based curing systems
- Enhances crosslink density
- Improves cure rate and efficiency
- Stabilizes rubber compounds
- Improves heat resistance and durability
Chemical Interaction
Zinc Oxide reacts with stearic acid to form zinc stearate, which then activates accelerators like:
- MBT (Mercaptobenzothiazole)
- MBTS (Dibenzothiazyl Disulfide)
- CBS (N-Cyclohexyl-2-benzothiazole sulfenamide)
- TBBS (N-tert-butyl-2-benzothiazole sulfenamide)
- TMTD (Tetramethylthiuram Disulfide)
This reaction is essential for efficient vulcanization and optimal mechanical properties.
