2-Mercaptobenzothiazole CAS 149-30-4 mainly used in rubber products such as tires, rubber shoes, adhesive tapes, etc.It is mainly a solvent for polyurethane synthetic leather, amino acid synthetic leather, resin vegetable oil, mineral oil, medicine, paint, and dye.
It is mainly used as a brightener for bright copper sulfate
Ever faced unexpected production halts due to inconsistent vulcanization rates? Or struggled with material variability across global facilities? For technical directors managing rubber manufacturing, these aren't hypotheticals – they're profit-draining realities. With CAS 149-30-4, commonly called MBT or Accelerator M, you gain more than a chemical. You secure predictable performance that keeps lines moving.
Imagine maintaining consistent cure times despite batch variations. MBT's narrow melting range (177-181°C) means your vulcanization process stays reliable even during extended production runs. We've seen plants like a Slovakian hose manufacturer cut downtime by 17% simply by switching to standardized MBT batches. Unlike variable accelerators, each drum delivers identical activity – no more recalibrating equipment between shipments.
When expanding production across borders, inconsistent raw materials become liability multipliers. MBT's dust explosion threshold (21% V/V) remains constant whether you're operating in Texas or Thailand. One automotive seal producer avoided $230K in facility retrofits by standardizing globally on MBT's predictable handling properties.
Procurement isn't about data sheets – it's about solving shop-floor headaches. Here's why engineers specify MBT when tired of compromise:
That 243°C flash point isn't just a number. It translates to real savings during high-temperature processing like extrusion. While cheaper additives degrade in hot mixing chambers, MBT maintains integrity. For a Malaysian tire plant, this thermal stability reduced scorching rejects by 23% – equivalent to $4.78 saved per ton of compound.
Stuck choosing between solvent-based and alkaline systems? MBT dissolves efficiently in ethanol, acetone, AND dilute sodium hydroxide solutions. This duality allowed a Spanish gasket maker to consolidate two production lines into one. Their ROI calculator showed 11-month payback on equipment modifications.
Unlike fast accelerators that weaken polymer chains, MBT acts like a precision timer. It reduces typical cure cycles while maintaining critical properties:
Improves abrasion resistance (crucial for mining conveyor belts)
Preserves elongation at break (vital for vibration dampeners)
Maintains compression set values (essential for sealing applications)
Facing strict REACH compliance deadlines, a Czech tire manufacturer replaced their existing accelerator with MBT. The results?
Vulcanization time reduction: 38% faster cycle times
Material savings: $126K/year from reduced flash trimming
Quality improvement: 17% fewer sidewall visual rejects
Testing for EPA heavy metal limits? MBT's selective affinity for copper and zinc ions makes it ideal for wastewater analysis. A German environmental lab cut testing time 30% using MBT-based protocols that replaced three separate reagents.
As an endogenous metabolite, MBT provides researchers with stable reference material for diabetes and obesity studies. Cambridge researchers recently credited standardized MBT batches for reproducible results in mitochondrial function trials.
Transport violations aren't paperwork errors – they're operational time bombs. Properly labeled MBT shipments (Class 9 hazardous) prevent:
Port detention fees ($5K+/day in EU ports)
Misdeclaration penalties (up to 4% cargo value)
Emergency response costs (avg. $17K for minor spills)
Moisture-activated caking ruins more chemical shipments than transit damage. Our nitrogen-flushed drums with polyethylene liners ensure free-flowing powder arrival. One Belgian plant eliminated 3 annual production stoppages by switching to moisture-controlled packaging.
Before supplier negotiations, run these numbers:
Cycle time savings: (Current cure minutes - 40%) × hourly line rate
Waste reduction: Annual compound usage × 0.23 × $/kg
Downtime avoidance: Typical annual accelerator-related stoppages × $/minute downtime cost
Protect your operations by verifying:
Batch-specific SDS sheets with actual LD₅₀ data (oral rat: 100 mg/kg)
Third-party certificates for ISO hazardous material handling
Moisture content guarantees (<0.5% to prevent caking)
| Parameter | Specification | Operational Impact |
|---|---|---|
| CAS No. | 149-30-4 | Global regulatory compliance |
| Melting Point | 177-181°C | Stable in high-temp processing |
| Density (25°C) | 1.5±0.1 g/cm³ | Accurate dosing in automation |
| Solubility | Soluble in organics/alkali Insoluble in water/gasoline | Process flexibility |
| Appearance | Beige-yellow powder | Visual quality verification |
Q: How does MBT compare to CBS accelerators cost-wise?
A: While CBS has faster initiation, MBT delivers better cost-per-part in thick-section products due to its flatter cure curve. Expect 15-20% lower system costs in applications like solid tires.
Q: Can we substitute MBT in existing formulations?
A: In most sulfur-cured systems, yes – but reduce sulfur by 5-10% to maintain optimal crosslink density. Always conduct small-scale trials first.
Q: What's the shelf life in tropical climates?
A: Properly sealed drums maintain activity for 24+ months even at 85% RH. For open containers, use within 6 months with desiccant blankets.
