Bis[3-(triethoxysilyl)propyl]tetrasulfise

Chemical name	Bis[3-(triethoxysilyl)propyl]tetrasulfise
Structural Formula
Property	CAS NO.:40372-72-3 Density(25°C),g/cm³：1.060-1.100 Total Sulfur,%：22 Boiling Point ：250°C Flash Point：106°C Refractive Index(n_D²⁰):1.4600-1.5000 Appearance：Yellow or light yellow transparent liquid. Dissolvability: Be soluble in organic solvent. It is almost insoluble in water.
Application	Si69 is a kind of silane coupling agent with multiple functional groups successfully used in rubber industry to improve modulus and tensile strength of rubber, to reduce the compound viscosity and save process energy consumption. It is especially applicable for polymers with double bond or rubber formulation with hydroxyl fillers. The suitable fillers include silica, silicate, clay, etc. The suitable rubber include natural rubber (NR), Butadiene styrene rubber (SBR), Isoprene rubber (IR), Butadiene rubber (BR), Acryloni-trile butadiene rubber (NBR), Ethylene propylene diene rubber (EPDM), etc.
