Key Applications
- Tire Manufacturing: Serves as a primary accelerator in the production of tire treads, casings, and inner tubes, offering excellent physical properties and aging resistance to the vulcanizates.
- Industrial Rubber Products: Extensively used in manufacturing conveyor belts, rubber hoses, V-belts, and heavy-duty industrial shock absorbers.
- Footwear & Cables: Applied in the vulcanization of rubber shoe soles and durable rubber cable insulation.
- Synergistic Use: Often used in combination with other secondary accelerators (such as DPG, TMTD, or sulfenamides) to fine-tune the vulcanization speed and improve the cross-linking density.
Packaging & Storage
We provide durable, moisture-resistant packaging strictly tailored for bulk solid chemical export.
- 25 KG Multi-wall paper bag with a PE inner liner.
- 25 KG PP woven bag.
- 500 KG / 1000 KG FIBC Jumbo Bags (Available upon request for large-scale operations).
Storage Conditions: Store in a cool, dry, and well-ventilated indoor warehouse. Keep away from moisture, heat, and direct sunlight. Ensure containers are tightly sealed when not in use. Do not store together with strong oxidizers or acids.
⚠️ Safety & Transport Information
- Transport Classification: Classified as Class 9 (Environmentally Hazardous Substance, Solid, N.O.S.).
- UN Number: UN 3077 | Packing Group: III
- Handling Precautions: MBTS is toxic to aquatic life with long-lasting effects and may cause allergic skin reactions. Operators should wear appropriate PPE including dust masks, safety goggles, and protective gloves during handling. Ensure adequate dust extraction and ventilation in the mixing area.
