Coupling Agent Si-69 Active Ingredient Bis(triethoxysilylpropyl) tetrasulfide Chemical Formula: C18H42O6S4Si2 Molecular Weight M.W: 538.95 CAS No.: 40372-72-3 EINECS No.: 254-896-5 Properties: On one hand, it chemically bonds with highly dispersed fillers such as white carbon black, and on the other hand, it bonds with rubber, resulting in excellent dynamic and static physical properties after vulcanization. It greatly reduces the viscosity during mixing; improves the wear resistance and modulus of the rubber compound. Dosage: Added together with reinforcing agents, 5-20% of the amount of white carbon black, 1.0-2.0% of the amount of clay and mica powder. Applications: Suitable for tires, shoe soles and rollers, rubber hoses, rubber belts, V-belts, etc.; used as wear-resistant and reinforcing agents in rubber products such as tires. Typical Data: Flash point: ≥100℃ Total sulfur content: ≥22.5% Chlorine content: ≤0.6% Density: 1.08-1.09g/cm3 Highly Dispersed Masterbatch |Product Name|Active Content %|Color|Filtration (μm)|Carrier Type|Mooney Viscosity ML(1+4) at 50℃ Typical Value|Density (g/cm3) Typical Value| |---|---|---|---|---|---|---| |Actmix? Si69-50GE F200|50|Pale yellow|200|EPDM/EVM|30-70|1.30| *The carrier type can be customized according to customer requirements. In addition to EPDM/EVM carriers, nitrile rubber, styrene-butadiene rubber, acrylate rubber and epichlorohydrin rubber carriers are also available. Safety and Toxicity: Please refer to the relevant Material Safety Data Sheet (MSDS). Packaging and Storage: Net weight 20kg in cartons, with 4 bags of 5kg vacuum-packed particles each; 600kg per pallet. Store in a cool, dry place, sealed in original packaging for 1 year. If the particles are completely hardened during storage, stop using them. Compared with traditional liquid Si69, Actmix Si69-50GE F200 has the following advantages: 1. Si69-50 masterbatch is wrapped with rubber carrier, which reduces the water absorption of Si69 and effectively ensures the stability and activity of Si69; 2. The masterbatch does not agglomerate at room temperature, making batching convenient and accurate; 3. It has low Mooney viscosity at low temperatures such as 50℃, improving the dispersion quality of Si69 in the rubber compound; 4. The masterbatch is filtered during granulation, contains no impurities, will not clog the screen during extrusion products, reduces the reject rate and improves production efficiency; 5. It has good compatibility with different types of rubber.
