Description

n-Benzylbenzothiazole-2-Sulfenamide is a specialized sulfenamide accelerator used primarily in the rubber vulcanization industry. This compound is valued for its ability to provide a delayed action onset, ensuring optimal processing safety and superior final crosslink density in rubber products. It is an essential chemical for manufacturers requiring precise control over cure characteristics and enhanced physical properties in their elastomer formulations.

Application

• Primary delayed-action accelerator for sulfur vulcanization of natural and synthetic rubbers.
• Used in the production of tire components (e.g., treads, sidewalls) to improve durability and aging resistance.
• Formulation of industrial rubber goods such as belts, hoses, seals, and gaskets.
• Enhances the mechanical properties and reversion resistance in thick-section rubber articles.
• Can be used in combination with other accelerators like thiazoles or guanidines for synergistic curing systems.
• Applicable in the compounding of EPDM and other specialty elastomers.
