Grade: CG-Si75

Bis(triethoxysilylpropyl) disulfide

CG-Si75 (Bis(triethoxysilylpropyl) disulfide) is a multifunctional silane coupling agent and tire additive successfully applied in the rubber industry. It improves the elastic modulus and tensile strength of rubber, significantly enhances wear resistance and compression performance, while reducing rubber viscosity and saving processing energy.

Packaging and Storage

This product can be packaged in 25 kg plastic drums, 200 kg plastic drums, or steel drums. Other package sizes are available upon request. Store in a cool, well-ventilated, dry place in tightly sealed containers, protected from light. Keep away from moisture and sources of ignition. Ensure the lid is tightly sealed and effectively isolates the product from air; moisture in the air can react quickly, thereby leading to hydrolysis and polymerization. Shelf life in the original unopened packaging is one year. This product is irritating to skin and eyes. If it contacts skin, wash with soap. If it contacts eyes, rinse immediately with plenty of water.

Application

  • CG-Si75 acts as a tire rubber industry additive: improves wear resistance, reduces hysteresis, enhances modulus, maximizes adhesion properties, improves processing performance, tread wear resistance, heat resistance, bonding between tire body and fillers, and bonding in tire cushion layers.

  • CG-Si75 is used in the modification of white carbon black/silica industry: modifies white carbon black/silica to promote their dispersion in rubber, increases bound rubber content, wet skid resistance, and wear resistance of carbon black/rubber composites, while reducing rolling resistance.

  • CG-Si75 serves the rubber additive industry: improves the performance of rubber additives and enhances the strength of subsequent rubber products.

  • CG-Si75 is suitable for fillers including white carbon black, silicates, clay, mica powder, chalk, etc. Suitable rubbers include natural rubber (NR), styrene-butadiene rubber (SBR), isoprene rubber (IR), butadiene rubber (BR), nitrile rubber (NBR), and ethylene propylene diene monomer (EPDM) rubber.

  • CG-Si75 applies to the footwear rubber industry: improves the stability of rubber systems, enhances yellowing resistance, and increases the tear strength of rubber used in shoe soles.
