Applications

Si69-B is a mixture of Si69 silane coupling agent and N330 carbon black. While performing the same function as Si69, it is more conve- nient to operate. Its application as a rubber and tire additive improves the physical and mechanical properties of rubber, significantly increasing tensile strength, tear resistance, wear resistance, and reducing permanent deformation. At the same time, it can also reduce rubber viscosity and improve processing performance. Suitable polymers include natural rubber (NR), isoprene rubber (IR), styrene butadi- ene rubber (SBR), butadiene rubber (BR), nitrile rubber (NBR), ethylene propylene diene monomer (EPDM), etc.
