Application：

This product is a mixture of silane coupling agent Si-75 and N330 carbon black. It has the same function as Si-75 and is more convenient for production.

This product is a multifunctional organosilicon coupling agent that has been successfully used in the rubber industry. Its function is to improve the elastic modulus and tensile strength of rubber, significantly improve the wear resistance and compression performance of rubber, reduce rubber viscosity and save processing energy. Suitable fillers include silica, silicates, chalk, etc.; suitable rubbers include natural rubber (NR), styrene butadiene rubber (SBR), isoprene rubber (IR), butadiene rubber (BR), nitrile rubber (NBR) and ethylene-propylene-diene rubber (EPDM), etc.

This product can provide more reliable scorch safety due to the lower reactive disulfane functional group.
