Description

n-Cyclohexyl-2-benzothiazolesulfenamide is a critical secondary vulcanization accelerator widely used in the rubber manufacturing industry. Its primary value lies in providing a delayed action or "scorch safety" during the vulcanization process, allowing for longer processing times and improved safety in production. This compound is essential for manufacturers of tires, conveyor belts, hoses, and other high-performance rubber goods who require precise control over curing characteristics and final product durability.

Application

• Primary Vulcanization Accelerator in Rubber Compounding: Used extensively in the production of natural rubber (NR), styrene-butadiene rubber (SBR), and polybutadiene rubber (BR) for tires, including treads, sidewalls, and carcasses.
• Secondary Accelerator in Synergistic Systems: Often combined with primary thiazole accelerators (like MBT or MBTS) to activate and enhance the curing efficiency and physical properties of the final rubber product.
• Manufacture of Mechanical Rubber Goods: Key component in formulations for conveyor belts, hoses, seals, gaskets, and vibration dampeners, where scorch delay and good aging resistance are required.
• Cable and Wire Insulation: Employed in the cross-linking of rubber compounds used for electrical insulation and jacketing.
• Footwear and Sporting Goods: Used in rubber soles, athletic surfaces, and other molded rubber items.
• Non-Tire Automotive Components: Applied in the production of engine mounts, bushings, and other under-hood or chassis components.

Quality Control

Our n-Cyclohexyl-2-benzothiazolesulfenamide is manufactured under a strict quality management system to ensure batch-to-batch consistency and high performance in demanding industrial applications. Each lot is tested against rigorous internal specifications, which typically include assay, melting point, and ash content. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance and regulatory compliance needs.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after initial opening to prevent moisture absorption, which can affect product performance.
