Description

Diisopropyl Xanthogen Polysulphide is a specialized organosulfur compound primarily utilized as a high-performance vulcanization accelerator and sulfur donor in the rubber industry. Its unique polysulfide structure enables efficient cross-linking, enhancing the physical properties and aging resistance of elastomers. This chemical is essential for manufacturers of industrial rubber goods, such as hoses, seals, and conveyor belts, who require reliable and consistent curing performance.

Application

• Rubber Vulcanization: Acts as a primary or secondary accelerator in the sulfur vulcanization of natural and synthetic rubbers, including SBR, NBR, and EPDM.
• Sulfur Donor Agent: Provides a controlled release of sulfur during the curing process, improving the efficiency of cross-link formation and reducing sulfur bloom.
• Rubber Reclaiming: Used in the devulcanization process for rubber recycling, helping to break down sulfur cross-links in scrap rubber.
• Oil-Resistant Rubber Formulations: Imparts excellent aging and heat resistance in rubber compounds designed for contact with oils and fuels.
• Technical Rubber Goods: Key component in the production of durable mechanical goods like gaskets, O-rings, and industrial rollers.
• Tire Manufacturing: Employed in specific tire component formulations to optimize cure characteristics and final product durability.

Quality Control

Our Diisopropyl Xanthogen Polysulphide is manufactured under strict quality control protocols to ensure batch-to-batch consistency and performance reliability. Production adheres to ISO 9001 quality management standards. A comprehensive Certificate of Analysis (COA) detailing purity, sulfur content, and other critical parameters is provided with every shipment to guarantee the material meets your specific formulation 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 material is easily oxidized and should be kept under an inert atmosphere or in a sealed container to minimize contact with air. Keep away from heat, sparks, and open flame.
