Main Applications

1.Bis-[3-(triethoxysilyl)propyl]-tetrasulfide is a silylation coupling agent and modifier that has been used to design a new generation of sustainable self-healing styrene-butadiene compounds;
2.Widely used in radial tires and rubber tire treads, carcasses, tire outer walls, solid rubber tire rubber roller surfaces and other rubber products;
3. SF-S069 is a multifunctional silane coupling agent that has been successfully used in the rubber and plastics industry. Its application can improve the physical and mechanical properties of rubber, and its tensile strength, tear resistance, and wear resistance can be significantly improved, the permanent deformation can be reduced, and it can also reduce the viscosity of the rubber compound and improve the processing performance. Especially suitable for vulcanized rubber systems using silica or silicate as reinforcing agents. Applicable fillers include silica, talc, clay, mica powder, clay, etc. Applicable polymers include NR, IR, SBR , BR, NBR, EPDM, etc.
