For professionals in the rubber processing industry, understanding the chemical additives used is crucial for optimizing product quality and manufacturing efficiency. Among the essential components is Rubber Accelerator MBTS, also known as Dibenzothiazole Disulfide, with the CAS number 120-78-5. As a leading manufacturer and supplier, we are committed to providing detailed information about this vital chemical intermediate. This article aims to shed light on the technical aspects and benefits of MBTS, particularly for those involved in tire manufacturing and other industrial rubber applications.

MBTS is a thiazole-type accelerator widely recognized for its effectiveness in sulfur vulcanization systems for various elastomers, including Natural Rubber (NR), Styrene-Butadiene Rubber (SBR), Nitrile Butadiene Rubber (NBR), and Ethylene Propylene Diene Monomer (EPDM). Its chemical structure, C14H8N2S4, and molecular weight of approximately 332.44 g/mol contribute to its unique performance characteristics. A key feature of MBTS is its ability to provide a flat and moderately fast cure rate, which means it offers a good balance between processing time and cure completion. Unlike some other accelerators, it exhibits a higher vulcanization temperature, leading to enhanced delayed action. This delayed action is critical for preventing scorching during the manufacturing process, thereby improving safety and reducing material waste.

The technical specifications for MBTS typically include a purity of 95.0% minimum, with a loss on drying not exceeding 0.40% and ash content below 0.50%. Its appearance is generally a grayish-white to light yellow powder or granule, with a melting point typically above 164.0°C. These properties make it a reliable and consistent performer in rubber formulations. For businesses looking to purchase MBTS, understanding these specifications ensures that they are acquiring a product that meets stringent quality standards. We, as a dedicated manufacturer, ensure that our MBTS adheres to industry benchmarks, such as GB/T 11408-2013.

The applications for MBTS are extensive and vital to the performance of many rubber products. In the tire industry, it is a key accelerator for producing passenger car radial (PCR) tires, contributing to their durability, traction, and overall safety. For industrial rubber goods, such as hoses, belts, and specialized molded parts, MBTS ensures the necessary mechanical strength and resilience. Its versatility allows it to be used alone or in synergy with other accelerators, providing formulators with flexibility. We encourage companies seeking to buy MBTS to consider its benefits for their specific production needs. Inquiring about MBTS price from a trusted supplier ensures you receive both quality and value.

In essence, Rubber Accelerator MBTS (DM) is a cornerstone chemical for modern rubber manufacturing. Its technical properties and performance benefits make it indispensable for achieving high-quality tires and industrial rubber products. As a reliable manufacturer and supplier from China, we are proud to offer this essential intermediate.
