Description

Dicyclopentamethylenethiuram Disulfide CAS NO 94-37-1 is a high-performance sulfur-containing organic compound widely recognized as an ultra-accelerator and vulcanizing agent in polymer science. Its primary value lies in significantly enhancing the speed and efficiency of the rubber vulcanization process, leading to improved physical properties in the final elastomer. This chemical is essential for manufacturers in the rubber and tire industries seeking to optimize production cycles and achieve superior product durability, heat resistance, and aging characteristics.

Application

• Primary Vulcanization Accelerator in the production of natural rubber (NR), synthetic rubber (SBR, NBR), and latex compounds.
• Ultra-Accelerator for EPDM (Ethylene Propylene Diene Monomer) rubber, enabling efficient cross-linking.
• Secondary Accelerator in synergistic blends with thiazoles or sulfenamides to boost cure rates and performance.
• Manufacturing of Technical Rubber Goods such as seals, gaskets, hoses, and conveyor belts requiring fast curing cycles.
• Tire Industry Component for specific compounds where rapid vulcanization is critical.
• Cross-linking Agent for certain specialty polymers and cable insulation materials.
• Agricultural Chemical Intermediate in the synthesis of certain fungicides and pesticides.

Quality Control

Our Dicyclopentamethylenethiuram Disulfide is manufactured under a stringent quality management system to ensure batch-to-batch consistency and high purity. The product undergoes comprehensive analytical testing, including assay, melting point determination, and ash content analysis, to meet exacting industrial specifications. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee compliance with your technical requirements.

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); therefore, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from heat, sparks, and open flame.
