Application |
In rubber industry, it can improve properties of white canborblack and other inorganic filler in the rubber matrix and vulanized rubber. Modify features: reduce the viscosity of colloidal, improve mobility,increase the interaction between the filler and the raw rubber, increase reinforcing properties, improve the tensile strength and tear strengthof vulcanizates, reduce the wear volume, permanent compression set, higher density of sulfur, improve the heat resistance, reduce heatand improve the product heat. |

Bis [3- (triethoxysilylpropyl)] tetrasulfide, commonly known as Si69, is an organic silicon compound containing sulfur and silicon. Si69 has two triethoxysilylpropyl chains bridged by tetrasulfide, which gives it special applications in enhancing the adhesive properties and temperature resistance of materials. It is commonly used to manufacture high-performance adhesives and sealants, especially in environments that require high temperature resistance and chemical corrosion resistance. Si69 forms chemical bonds with inorganic substrates through its silane portion, and its sulfur content helps improve the thermal stability and elasticity of the product.
