Bis[3-(triethoxysilyl)propyl]tetrasulfide CAS No:40372-72-3 C18H42O6S4Si2

Applications

1. Bis-[3-(triethoxysilyl)propyl] tetrasulfide is a silane coupling agent and modifier that has been used to design a new generation of sustainable self-healing styrene-butadiene compounds.

2. It is widely used in rubber products such as radial tires and their treads, carcasses, sidewalls, as well as the surfaces of solid rubber rollers.

3. It is a multifunctional silane coupling agent that has been successfully used in the rubber and plastics industry. Its application improves the physical and mechanical properties of rubber, significantly enhancing tensile strength, tear resistance, and abrasion resistance, while reducing permanent deformation. It also lowers compound viscosity and improves processability. It is particularly suitable for vulcanized rubber systems reinforced with silica or silicates. Suitable fillers include silica, talc, clay, mica powder, and kaolin, while suitable polymers include NR, IR, SBR, BR, NBR, and EPDM.
