Description

Zinc Dimethyldithiocarbamate is a highly effective organosulfur compound widely used as an ultra-accelerator and vulcanization activator in the rubber industry. Its primary value lies in its ability to significantly reduce curing times while improving the physical properties of the final rubber product, offering manufacturers enhanced efficiency and material performance. This chemical is essential for producers of automotive components, industrial hoses, seals, and other high-performance elastomers who require reliable and consistent processing aids.

Application

• Primary Vulcanization Accelerator in the production of natural rubber (NR), styrene-butadiene rubber (SBR), and nitrile rubber (NBR).
• Secondary Accelerator/Activator in thiazole- and sulfenamide-accelerated systems to boost cure rate and efficiency.
• Manufacturing of Technical Rubber Goods such as seals, gaskets, hoses, conveyor belts, and footwear.
• Automotive Rubber Components including engine mounts, vibration dampers, and tire inner liners.
• Agricultural and Industrial Applications in rubber parts for machinery and equipment.
• Latex Compounding for dipped goods like gloves and balloons.
