Vulcanization & Accelerators Nocil
Vulcanization of rubbers by sulfur alone is an extremely slow and inefficient process. The chemical reaction between sulfur and the Rubber Hydrocarbon occurs mainly aC (doublet the C = bonds ) and each crosslink requires 40 to 55 sulphur atoms (in the absence of accelerator). The process takes around 6 hours at 140°C

- Is ZDBC a good accelerator?
- ZDBC is a versatile rubber accelerator with notable characteristics, including fast acceleration, moderate reactivity, good scorch safety, and excellent vulcanization properties. It finds widespread application in various rubber products, including tires, industrial rubber goods, footwear, and automotive parts.
- What is ZDBC (zinc dibutyl dithiocarbamate)?
- ZDBC (Zinc Dibutyl Dithiocarbamate) is a commonly used rubber accelerator that plays a crucial role in the production of rubber products. This article aims to provide an overview of ZDBC, its characteristics, its applications in rubber product manufacturing, potential product combinations, and important considerations for commercial procurement. 1.
- How does ZDBC impact rubber processing?
- ZDBC has a significant impact on the cost and efficiency of rubber processing. It offers long-term cost savings through enhanced durability and reduced replacements. Additionally, it optimizes processing workflow by accelerating curing times and improving qualities like chemical and weather resistance.
- How does ZDBC vulcanize rubber?
- In the vulcanization process, ZDBC reacts with sulfur to form cross-links between the polymer chains of the rubber, thereby enhancing the rubber’s durability and resistance to deformation. Despite its high reactivity, ZDBC maintains excellent scorch safety, making it suitable for a wide range of rubber products.
- What is ZDBC used for?
- ZDBC confers several advantages when used in the production of both natural and synthetic rubber, including: Improved Product Performance: ZDBC enhances the physical and chemical properties of rubber, allowing it to withstand demanding conditions. This results in a higher quality product that outperforms those not treated with ZDBC.
- What type of compound is ZDBC?
- ZDBC is an organic compound belonging to the dithiocarbamate class of accelerators. It is a white to light yellow powder with a mild odor. Chemically, it consists of a zinc atom attached to two butyl groups and a dithiocarbamate functional group. ZDBC is known for its excellent solubility in rubber and compatibility with various types of rubber. 2.
