Description

Diisobutylthiuram Disulfide is a sulfur-containing organic compound widely utilized as a critical vulcanization accelerator in the rubber industry. Its primary value lies in its ability to significantly enhance the speed and efficiency of the vulcanization process, improving the final physical properties of rubber products. This chemical is essential for manufacturers in the automotive, industrial goods, and specialty elastomer sectors seeking to optimize production cycles and product performance.

Application

• Primary Vulcanization Accelerator for natural rubber (NR) and synthetic rubbers like styrene-butadiene rubber (SBR) and nitrile rubber (NBR).
• Secondary Accelerator in synergistic systems with thiazoles or sulfenamides to fine-tune cure characteristics and scorch safety.
• Used in the production of technical rubber goods, including hoses, seals, gaskets, and conveyor belts.
• Formulation component for automotive rubber parts such as engine mounts, vibration dampers, and tire components.
• Employed in the manufacture of cable sheathing and insulation due to its favorable curing profile.
• Applicable in certain adhesive and sealant formulations requiring elastomeric properties.

Quality Control

Our Diisobutylthiuram Disulfide is produced under stringent quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot undergoes comprehensive analytical testing, including assay, melting point determination, and ash content analysis. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee compliance with agreed specifications and industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); therefore, containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality.
