| Use | Bis-[3-(triethoxysilicon) propyl]-tetrasulfide is a silanized coupling agent and modifier, Has been used to design a new generation of sustainable self-healing styrene-butadiene compounds. It is widely used in rubber products such as tread, carcass, outer wall of radial tires and rubber tires. It is a multifunctional silane coupling agent that has been successfully used in the rubber and plastic industry. Its application improves the physical and mechanical properties of rubber, the tensile strength, tear strength, wear resistance, etc. can be significantly improved, and the permanent deformation can be reduced, at the same time, it can also reduce the viscosity of the rubber and improve the processing performance. It is particularly suitable for vulcanized rubber systems with silica or silicate as reinforcing agents, and its applicable fillers include silica, talcum powder, clay, mica powder, clay, etc., and applicable polymers include NR, IR, SBR, BR, NBR, EPDM, etc. |
