In the world of rubber manufacturing, choosing the right accelerators is essential for achieving efficient vulcanization, optimal mechanical properties, and long-lasting performance. Two of the most widely used accelerators are MBT (Mercaptobenzothiazole) and MBTS (Dibenzothiazyl Disulfide).
As a leading MBT & MBTS accelerator manufacturer and supplier in India, Arihant Reclamation Pvt. Ltd. (ARPL) delivers consistent quality, technical expertise, and a commitment to supporting your production needs—whether you’re making tyres, footwear, hoses, or molded rubber goods.
Understanding MBT & MBTS Accelerators
MBT Accelerator (2-Mercaptobenzothiazole)
MBT is a classic primary accelerator that promotes the vulcanization of natural and synthetic rubber. It is known for:
| Property | Details |
|---|---|
| Chemical Name | 2-Mercaptobenzothiazole |
| Formula | C7H5NS2 |
| Appearance | Pale yellow powder |
| Melting Point | Min. 170°C |
| Usage | Main or secondary accelerator in NR, SBR, NBR |
Advantages:
- Ensures good aging properties of vulcanized rubber
- Suitable for transparent or lightly colored products
- Provides moderate cure rate with excellent scorch safety
MBTS Accelerator (Dibenzothiazyl Disulfide)
MBTS is a delayed-action accelerator derived from MBT. It’s widely used when better scorch control is needed.
| Property | Details |
|---|---|
| Chemical Name | Dibenzothiazyl Disulfide |
| Formula | C14H8N2S4 |
| Appearance | Light yellow or grayish powder |
| Melting Point | Min. 166°C |
| Usage | Primary accelerator in general purpose rubbers |
Advantages:
- Slower curing at processing temperatures, reducing risk of premature vulcanization (scorch)
- Gives uniform cross-linking and stable mechanical properties
- Ideal for large, thick articles requiring longer cure cycles
Applications of MBT & MBTS in Rubber Industries
| Industry | Role of MBT / MBTS Accelerators |
|---|---|
| Tyre Manufacturing | Enhance vulcanization for tread and sidewalls |
| Footwear Soles | Improve abrasion resistance and elasticity |
| Conveyor Belts & Hoses | Ensure heat and aging stability |
| Automotive Moldings | Balanced cure and dimensional accuracy |
| Rubber Sheets & Mats | Better tensile strength & elongation |
