In the global rubber manufacturing sector, driving processing efficiency while locking in optimal material characteristics is critical. Vulcanization Accelerator MBT (also widely known as M) is a staple acid accelerator trusted worldwide. Chemically classified as 2-Mercaptobenzothiazole (CAS No. 149-30-4), MBT acts as a fast primary accelerator providing a relatively low curing critical temperature. It yields highly cross-linked networks with broad processing compatibility, serving as the cornerstone for a massive array of heavy industrial and molded mechanical goods.

Why Choose Our MBT (M) Accelerator?
- ✓ Rapid Curing Profile: MBT acts as a swift primary accelerator, imparting fast vulcanization rates while establishing a highly stable, flat cure plateau that reduces the risk of over-curing.
- ✓ Excellent Structural Properties: Vulcanizates accelerated with MBT exhibit high tensile strength, outstanding modulus, good physical wear fatigue, and superior resistance to heat aging.
- ✓ Excellent Secondary Synergies: It blends smoothly with basic accelerators such as DPG, TMTD, or sulfenamides to create highly effective secondary systems, allowing compounders to calibrate custom scorch and cure behaviors.
Primary Applications
MBT is highly effective in natural rubber (NR), styrene-butadiene rubber (SBR), butadiene rubber (BR), and nitrile rubber (NBR) compounding across multiple sectors:
Tire Component Layouts
Extensively applied in tire tread, carcass plies, sidewalls, inner tubes, and robust rubber wire skim compounds.
Industrial Goods
Perfect for heavy industrial conveyor belts, dynamic driving belts, high-pressure industrial hoses, and custom technical gaskets.
Consumer Footwear & Molded Goods
Widely chosen for athletic footwear outsoles, solid rubber wires/cables, surgical or industrial latex, and miscellaneous daily molded products.
Quality Assurance & Global Compliance
As a leading global partner in industrial manufacturing, we understand that chemical purity, structural consistency, and regulatory alignment directly influence your operational uptime. Our production facilities maintain rigorous quality benchmarks to support international delivery without supply chain disruptions:
- Advanced Analytical Quality Control: Every commercial batch of our Accelerator MBT (M) undergoes rigorous laboratory validation—including high-performance liquid chromatography (HPLC), capillary melting point testing, and precision ash analysis—ensuring a steady purity level that prevents variances during downstream factory mixing.
- Comprehensive International Regulatory Compliance: We maintain a proactive approach to global chemical governance. All export documentation is systematically updated to provide comprehensive Safety Data Sheets (SDS), certificates of analysis (CoA), and registration structures fully matching regulatory frameworks such as EU REACH and US TSCA.
- Optimized Packaging & Supply Chain Resilience: To minimize workplace dust exposure and optimize automated material feeding systems, we supply our premium MBT in multi-layer moisture-resistant bags (25kg), heavy-duty bulk bags (FIBCs), or custom oiled configurations engineered to safeguard physical product stability during cross-border transit.
⚠ Storage & Handling Guidelines
Maintaining proper warehouse controls is essential to prevent the atmospheric degradation of Accelerator MBT (M). Because it is an acidic thiazole derivative, prolonged exposure to heat or humidity can lead to moisture absorption, material clumping (caking), or a slow decline in cross-linking efficiency.
- • Climate & Environmental Controls: Store the chemical in a cool, dry, and exceptionally well-ventilated dedicated industrial space. Keep the product strictly isolated from direct solar radiation, high-temperature utility piping, open flames, and basic (alkaline) chemical materials.
- • Packaging Management: Ensure that all multi-layer paper bags or bulk supersacks remain fully sealed during transit and warehousing. Partially consumed packages must be twisted and mechanically resealed immediately to block ambient moisture intake.
- • Shelf Life Stability: Under ideal, cool warehouse conditions, our premium MBT exhibits excellent chemical stability with a certified shelf life of 24 months from the date of manufacture. Implementing a strict First-In, First-Out (FIFO) material rotation system is strongly recommended.
