Description

Zinc Pentamethylenedithiocarbamate is a high-performance organometallic compound widely utilized as an ultra-accelerator in the rubber industry. Its primary value lies in providing exceptionally fast vulcanization rates, which significantly enhances production efficiency and improves the physical properties of the final rubber product. This chemical is essential for manufacturers in the automotive, industrial hose, and cable sectors seeking to optimize their curing processes and achieve superior product performance.

Application

• Rubber Vulcanization Accelerator: Primary use as a fast-acting, non-blooming accelerator for natural and synthetic rubbers, including SBR, NBR, and EPDM.
• Automotive Components: Production of high-performance seals, hoses, belts, and vibration dampeners requiring precise and rapid curing.
• Industrial Rubber Goods: Manufacturing of conveyor belts, rolls, gaskets, and technical molded articles.
• Wire & Cable Insulation: Used in the curing of rubber insulation and jacketing for electrical cables.
• Footwear & Sporting Goods: Formulation of rubber soles, grips, and other components needing excellent physical properties.
• Latex Dipped Goods: Acceleration of vulcanization in the production of latex gloves, balloons, and other dipped products.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from strong oxidizing agents and acids.
