For professionals in the rubber industry, understanding the fundamental properties and manufacturing processes of key additives is crucial for successful compounding. Rubber Accelerator CBS, chemically known as N-cyclohexyl-2-benzothiazolesulfenamide (CAS 95-33-0), stands out as a highly effective and widely used vulcanization accelerator. As a leading chemical supplier, we aim to shed light on this essential compound.

The chemical structure of CBS is central to its functionality. It features a benzothiazole ring linked to a cyclohexyl group via a sulfenamide bridge. This specific molecular arrangement imparts the compound's characteristic delayed-action properties. This means that during the initial stages of rubber mixing, CBS provides a degree of stability, preventing premature curing (scorch). This is a significant advantage for manufacturers, allowing for safer and more controlled processing of rubber compounds, especially in high-temperature environments. Once the vulcanization temperature is reached, the sulfenamide bond breaks, releasing active sulfur species that efficiently cross-link the rubber polymer chains.

The manufacturing process of CBS is a multi-step chemical synthesis that requires precise control to ensure purity and consistency. Typically, it begins with the reaction of aniline and carbon disulfide, followed by further reactions involving cyclohexylamine and sulfur. Each step is carefully managed for temperature, pressure, and reaction time to maximize yield and minimize impurities. As a reputable manufacturer, we adhere to stringent quality control measures throughout our production to deliver a product that meets high industry standards. Whether you are looking to buy CBS in bulk or require specific grades, our commitment to quality manufacturing ensures you receive a reliable product.

CBS is often described as a primary accelerator, but its performance is frequently optimized when used in conjunction with secondary accelerators like MBTS or DPG. This synergy allows compounders to achieve a balance of scorch safety, cure rate, and final physical properties. Its broad applicability in natural rubber and various synthetic rubbers, including SBR and EPDM, makes it a versatile choice for a wide range of rubber products, from tires and automotive parts to industrial belts and footwear.
