NINGBO INNO PHARMCHEM CO.,LTD. is proud to offer Zinc Dibutyldithiocarbamate (ZDBC), a versatile and highly effective rubber accelerator that plays a pivotal role in modern rubber manufacturing. This article explores the fundamental chemical properties of ZDBC and its wide-ranging applications, demonstrating why it is a preferred choice for optimizing rubber formulations. Understanding these aspects is crucial for manufacturers aiming to enhance product quality and process efficiency.

Chemically, ZDBC is classified as a dithiocarbamate. Its molecular formula, Zn[(C4H9)2NCS2]2, reveals a structure where a central zinc atom is chelated by two dibutyldithiocarbamate ligands. This specific arrangement confers upon ZDBC its unique reactivity and performance characteristics as a rubber accelerator. Its typical appearance is a white to light yellow powder, with a density of approximately 1.24 g/cm³. ZDBC is notably insoluble in water but soluble in organic solvents such as benzene and chloroform, which aids in its dispersion within rubber compounds. The initial melting point typically falls between 104-110 °C, indicating a good balance between stability during storage and reactivity during processing.

As an ultra-fast primary accelerator, ZDBC significantly reduces vulcanization times. This rapid action is a primary driver for its adoption in high-volume manufacturing. Furthermore, ZDBC provides excellent scorch safety, a critical factor that prevents premature curing during the mixing and shaping stages of rubber processing. This balance of speed and safety allows for greater control and reduces the risk of processing errors. For applications where preserving product integrity over time is crucial, ZDBC's ability to improve rubber aging resistance is highly valued. The meticulous control of ZDBC dosage for tires and other demanding items ensures that these properties are optimized.

The applications of ZDBC are extensive and varied. It is widely used in the production of tires, where its acceleration properties contribute to improved wear resistance and overall tire longevity. In the automotive industry, ZDBC is employed in manufacturing seals, gaskets, and hoses, enhancing their performance and durability. It is also a preferred accelerator for latex-based products, including rubber gloves and footwear, where its non-staining properties and ease of dispersion in aqueous systems are particularly advantageous. The ability to achieve transparent rubber products with ZDBC further expands its utility in niche applications.

The compatibility of ZDBC with sulfur and other common rubber additives, such as antioxidants and reinforcing fillers, allows for flexible formulation design.
