Description

n-(1,1,3,3-Tetramethylbutyl)Benzothiazole-2-Sulphenamide is a high-performance, delayed-action sulfenamide accelerator primarily used in the rubber vulcanization process. This compound matters for its ability to provide an excellent balance of processing safety and fast curing rates, which is critical for manufacturing high-quality rubber products with consistent physical properties. Industries such as tire manufacturing, industrial rubber goods, and automotive components rely on this accelerator to achieve optimal cross-linking efficiency and superior final product performance.

Application

• Primary accelerator in the vulcanization of natural rubber (NR) and synthetic rubbers like styrene-butadiene rubber (SBR).
• Critical component in the production of tire treads, sidewalls, and other tire compounds requiring good aging resistance and flex fatigue properties.
• Used in the manufacture of industrial rubber goods such as conveyor belts, hoses, seals, and gaskets.
• Formulation of mechanical rubber goods for the automotive industry, including engine mounts and bushings.
• Enhances the cure characteristics in compounds containing high levels of reinforcing fillers like carbon black and silica.
• Can be used in combination with other accelerators (e.g., thiurams, dithiocarbamates) to fine-tune scorch safety and cure speed.

Quality Control

Our n-(1,1,3,3-Tetramethylbutyl)Benzothiazole-2-Sulphenamide is manufactured under a stringent quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, melting range, and performance characteristics typical for rubber accelerators. Certificates of Analysis (COA) detailing assay, physical properties, and impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from heat, sparks, and open flame.
