Rubber Accelerator TMTD (TT): High-Efficiency Vulcanization Agent for Premium Rubber Products
In the rubber manufacturing ecosystem, vulcanization is the defining process that determines the performance, longevity, and commercial value of the final product. At the heart of this process lies the accelerator.
Rubber Accelerator TMTD (Chemical Name: Tetramethylthiuram Disulfide, commonly known as TT) is a classic, high-performance thiuram accelerator. Renowned for its rapid vulcanization speed, high cross-linking density, and broad compatibility, TMTD has become an indispensable additive for the production of tires, industrial seals, conveyor belts, and more.
Below, we analyze the core value of TMTD (TT) through technical specs, application scenarios, and performance data.
1. Core Features: The Guarantee of Efficient Vulcanization
Rubber Accelerator TMTD (TT) appears as a white or pale gray powder (or granule). It is odorless, non-toxic, and boasts excellent dispersion and compatibility. It is perfectly adapted for use with Natural Rubber (NR), Styrene-Butadiene Rubber (SBR), Nitrile Rubber (NBR), and most synthetic and reclaimed rubbers.
Key Performance Advantages:
- Superior Vulcanization Efficiency:As a fast-acting accelerator, TMTD significantly lowers the activation energy required for the reaction.
- Data: At standard curing temperatures (140-160°C), formulas containing TMTD reduce curing time by 30%-50%, boosting throughput and lowering energy costs.
- Stable Cross-Linking Structure:It promotes the formation of a high-density, uniform cross-link network. This directly improves mechanical properties.
- Data: Third-party testing shows that TMTD-optimized products see a 15%-25% increase in tensile strength and a 20%+ increase in tear strength.
- Versatile Application:It functions as a primary accelerator for rapid curing or as a secondary accelerator (booster) alongside thiazoles (like MBTS/DM) or sulfenamides (like CBS/CZ). It fits various processes, including ambient, medium, and high-temperature curing.
- Excellent Storage Stability:Stored in dry, ventilated conditions, TMTD remains stable for over 12 months without absorbing moisture or caking, ensuring dosing accuracy during production.
2. Technical Specifications (TDS)
High-quality rubber additives must rely on precise technical parameters. Our TMTD (TT) is manufactured strictly according to standard GB/T 11407-2013.

> Note: The above data represents typical mass-production values. We can provide customized parameter adjustments (e.g., oil-coated powder or granules) to meet specific processing requirements.
3. Applications: Enhancing Quality Across Industries
Due to its exceptional scorching resistance and curing speed, TMTD is deeply integrated into multiple industrial sectors.
A. The Tire Manufacturing Industry
Used in tire treads, sidewalls, and inner tubes, TMTD works synergistically with accelerators like CBS (CZ) and MBTS (DM).
- Benefit: Improves wear resistance and anti-aging properties.
- Impact: Tires using a TMTD curing system achieve a wear resistance index of 350+ (Industry average: ~280), extending service life by over 30%.
B. Rubber Seals & Gaskets
Seals demand high elasticity and compression set resistance. TMTD ensures uniform cross-linking.
- Benefit: Maintains sealing integrity in extreme temperatures (-40°C to 120°C) and high-pressure environments.
- Impact: Widely used in automotive engine gaskets and hydraulic O-rings, holding a market share of over 40% in premium seal manufacturing.
C. Conveyor & Transmission Belts
For industrial belts enduring constant tension and friction, TMTD is critical.
- Benefit: Enhances tensile strength (reaching 18MPa+) and reduces abrasion loss.
- Impact: In mining and port operations, belts cured with TMTD see a 40% extension in lifespan, significantly reducing downtime and replacement costs.
D. General Rubber Goods (GRG)
- Footwear: Improves the elasticity of shoe soles, allowing for flex resistance exceeding 100,000 cycles.
- Latex Products: In rubber gloves, it shortens curing time and improves tensile resilience for better user comfort.
