Description

N-Benzothiazol-2-Ylsulfanyl-N-tert-Butyl-Benzothiazole-2-Sulfenamide is a high-performance sulfenamide accelerator primarily used in the rubber vulcanization process. This compound is valued for its ability to provide a delayed action onset, ensuring optimal processing safety and superior final product properties. It is an essential chemical for manufacturers in the tire, automotive parts, and industrial rubber goods sectors seeking to enhance the durability and performance of their elastomeric products.

Application

• Primary Rubber Vulcanization Accelerator: Widely used as a delayed-action accelerator in the sulfur vulcanization of natural rubber (NR) and synthetic rubbers like SBR and BR.
• Tire Manufacturing: Critical for the production of tire treads, sidewalls, and other components requiring excellent flex fatigue resistance and aging properties.
• Technical Rubber Goods: Employed in the manufacture of conveyor belts, hoses, seals, and gaskets where high tensile strength and elasticity are paramount.
• Cable & Wire Insulation: Used in rubber compounds for electrical insulation due to its favorable curing characteristics and product stability.
• Footwear & Sporting Goods: Applied in rubber soles and other molded rubber items for consistent curing and good physical properties.
• Secondary Accelerator in Blends: Often used in combination with thiazoles or guanidines to modify cure rate and optimize the performance of complex rubber formulations.
