CAS NO.: 56706-10-6 Product appearance: colorless to light yellow transparent liquid Solubility: Soluble in most organic solvents, hydrolyzed in water Boiling point: N.A Flash point (closed cup):>100 ℃ Density (20 ℃): 1.03 ± 0.02 Refractive index (nD25): 1.450-1.465


Suitable for vulcanized rubber systems with reinforcing agents such as silica or silicates, it is a multifunctional organic silicon coupling agent that has been successfully applied in the rubber industry. Its function is to increase the elastic modulus and tensile strength of rubber, significantly improve its wear resistance and compression performance, while reducing rubber viscosity and saving processing energy consumption. The most suitable rubber formula for using hydroxyl fillers in double bond polymers or their blends. Suitable fillers include white carbon smoke, silicate, 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). Compared with tetrahydrosilane JH-S69, this product has a lower active disulfide functional group, which can provide more reliable coking safety.
