The complex process of rubber vulcanization relies heavily on specialized chemical additives, with accelerators playing a pivotal role in controlling the speed and efficiency of the curing reaction. Among the various classes of accelerators, sulfenamides, particularly N-Cyclohexyl-2-Benzothiazolesulfenamide (CBS, CAS 95-33-0), are indispensable for achieving optimal rubber properties. As a dedicated supplier of high-quality chemicals, we aim to shed light on the critical function of CBS in modern rubber manufacturing.

Sulfenamide Accelerators: A Class Apart

Sulfenamide accelerators are characterized by their 'delayed action' mechanism. This means they remain relatively inactive at lower processing temperatures, providing a crucial scorch delay. This delay allows ample time for mixing, extrusion, and molding of rubber compounds without premature vulcanization. Once the compound reaches a specific activation temperature, the sulfenamide bond breaks, releasing active sulfur-donating species that rapidly promote cross-linking. This dual action makes them highly efficient and safe for a wide range of rubber applications.

N-Cyclohexyl-2-Benzothiazolesulfenamide (CBS) – The Workhorse

CBS is arguably the most widely used sulfenamide accelerator globally. Its popularity stems from its excellent balance of scorch safety, cure rate, and the desirable physical properties it imparts to the vulcanized rubber. As a chemical manufacturer, we produce CBS with high purity, typically 97% min, ensuring that our clients can consistently achieve the performance they expect. When you buy N-cyclohexyl-2-benzothiazolesulfenamide from us, you are assured of a product that:

  • Offers Superior Scorch Protection: Critical for preventing production losses due to premature curing.
