Description

Zinc dibenzyldithiocarbamate (Zbdc, Ztc) is a high-performance organometallic compound widely used as an ultra-accelerator and secondary stabilizer in various polymer systems. This product is valued for its ability to significantly enhance the vulcanization efficiency and aging resistance of rubber compounds, leading to improved product durability. It is an essential material for manufacturers in the rubber, elastomer, and specialty polymer industries seeking to optimize processing times and final material properties. The compound is supplied under strict quality control to ensure batch-to-batch consistency for industrial applications.

Application

• Rubber Vulcanization: Primary use as a powerful ultra-accelerator in the sulfur vulcanization of natural rubber (NR), synthetic polyisoprene (IR), and butyl rubber (IIR), enabling faster cure rates and improved crosslink density.
• Elastomer Manufacturing: Employed in the production of technical rubber goods, seals, gaskets, hoses, and conveyor belts where precise curing control and heat resistance are critical.
• Polymer Stabilization: Acts as a secondary stabilizer or synergist in combination with primary antioxidants to protect polymers against thermal and oxidative degradation during processing and service life.
• Latex Compounding: Used in the formulation of dipped goods and foam latex products to control the vulcanization process and enhance physical properties.
• Adhesive and Sealant Formulations: Incorporated into solvent-based or hot-melt adhesive systems based on rubber to modify cure characteristics and improve bond strength and aging.
• Wire and Cable Insulation: Applied in the cross-linking of elastomeric insulation and jacketing materials to achieve superior electrical and mechanical performance.
