Bis(triethoxysilylpropyl)disulfide

Product Overview

Bis(triethoxysilylpropyl)disulfide is a premier organosilicon compound engineered specifically for high-performance rubber compounding. As a bifunctional silane coupling agent, it serves as a critical molecular bridge between inorganic fillers and organic polymer matrices. This chemical is extensively utilized in the modern tire industry, particularly for green tire technologies that demand low rolling resistance and superior wet grip performance. Our manufacturing process ensures consistent quality, making it a reliable choice for demanding industrial applications.

Key Performance Benefits

The incorporation of this disulfide silane into rubber formulations delivers measurable improvements in physical properties. By chemically bonding silica fillers to the rubber backbone, it significantly reduces filler aggregation and enhances dispersion. This results in a composite material with optimized dynamic mechanical properties. Key advantages include enhanced elastic modulus, superior tensile strength, and remarkable wear resistance. Furthermore, the agent helps reduce compound viscosity, facilitating easier processing and saving energy during manufacturing cycles.

• Improves bonding between silica fillers and rubber polymers
• Enhances wear resistance and compression set performance
• Reduces processing viscosity for better manufacturing efficiency
• Compatible with a wide range of synthetic and natural rubbers

Technical Specifications

Industrial Applications

This product is most suitable for rubber formulations utilizing hydroxyl-containing fillers within double bond-containing polymers or their blends. It is the industry standard for reinforcing white soot, silicate, and chalk fillers. The chemical exhibits excellent compatibility with various elastomer types, including Natural Rubber (NR), Styrene Butadiene Rubber (SBR), Isoprene Rubber (IR), Butadiene Rubber (BR), Nitrile Rubber (NBR), and Ethylene-Propylene-Diene Rubber (EPDM). It is particularly valued in the production of high-performance tires, conveyor belts, and mechanical rubber goods where durability is paramount.

Packaging and Storage

To maintain product integrity, we supply this material in standard 200Kg iron drums or 1000Kg IBC containers. Storage requirements dictate keeping the product in its original unopened container at temperatures of 25°C or below. Under these conditions, the shelf life is guaranteed for six months from the production date. Any expired product should only be utilized after passing rigorous quality control tests to ensure performance standards are met. Classified as non-dangerous goods, it allows for streamlined logistics and global shipping capabilities.
