At NINGBO INNO PHARMCHEM CO.,LTD., we believe that understanding the fundamental chemistry behind our products is crucial for our partners. Today, we focus on MBTS/DM (Dibenzothiazole Disulfide), a vital rubber accelerator that significantly influences the final properties of manufactured rubber goods. Its application is key to achieving the superior tensile strength, elasticity, and longevity that modern industries demand.

MBTS/DM is a core component in the rubber compounding process, acting as a sulfur donor that accelerates the vulcanization of both natural rubber (NR) and synthetic rubbers (SR). The scientific name, 2,2'-Dithiobis(benzothiazole), and its molecular formula, C14H8N2S4, highlight its chemical nature, which is optimized for efficient cross-linking. This process is fundamental to transforming raw rubber into durable, resilient materials.

The primary function of MBTS/DM as an accelerator for NR & SR is to promote vulcanization at a controlled, medium speed. This characteristic, combined with its high activation temperature, provides a critical safety margin during rubber processing. It prevents premature curing or scorching, allowing manufacturers ample time for mixing and shaping the rubber compound before the vulcanization reaction initiates. This controlled approach is essential for producing complex industrial parts and maintaining consistent product quality, making it a preferred choice for safe rubber vulcanization process operations.

When examining the MBTS DM powder properties, manufacturers will note its consistent appearance, typically as a white to light yellow powder or granules. Its high melting point and low moisture content are indicative of a stable chemical that can withstand processing temperatures. Furthermore, the minimal ash content and sieve residues ensure that the accelerator integrates smoothly into the rubber matrix, leading to a more uniform distribution of the vulcanizing agents. These detailed MBTS DM powder properties are crucial for achieving the desired physical characteristics in the final product.

The contribution of MBTS/DM to improved tensile strength and elasticity is a major reason for its widespread adoption. The efficient cross-linking it facilitates results in a rubber network that can withstand greater stress before breaking and return to its original shape after deformation. This is particularly important in applications like automotive tires, where dynamic forces are constantly applied, making it an excellent accelerator for tires manufacturing. The enhanced durability also extends to other industrial rubber products, such as seals, hoses, and vibration mounts, where resilience and longevity are critical performance indicators.

Moreover, MBTS/DM acts as an effective rubber aging resistance accelerator. This means that rubber products manufactured using this accelerator are better protected against degradation caused by environmental factors like heat, oxygen, and ozone. This inherent resistance to aging significantly extends the operational lifespan of rubber components, reducing the need for frequent replacements and contributing to overall cost-effectiveness for end-users. NINGBO INNO PHARMCHEM CO.,LTD. supplies MBTS/DM to ensure manufacturers can achieve these vital product attributes.

For any manufacturer looking to buy MBTS/DM and elevate the performance of their rubber products, understanding the precise rubber accelerator MBTS DM uses is paramount. From ensuring process safety to imparting superior mechanical properties and resistance to aging, MBTS/DM is a cornerstone additive for achieving excellence in the rubber industry.
