CG-Si69 is a kind of silane coupling agent with multiple functional groups successfully used in rubber industry to improve modulus and tensile strength of rubber, to reduce the compound viscosity and save process energy consumption. It is especially applicable for polymers with double bond or rubber formulation with hydroxyl fillers. The suitable fillers include silica, silicate, clay, etc. The suitable rubber include natural rubber (NR), Butadiene styrene rubber (SBR), Isoprene rubber (IR), Butadiene rubber (BR),Acrylonitrile butadiene rubber (NBR), Ethylene propylene diene rubber (EPDM), etc.

CG-Si50 is a mixture of CG-Si69 and carbon black. It has the same function as CG-Si69 and at the same time it is more convenient to operate. It works as the rubber, tire aids to improve the physical and mechanical properties. Tensile strength, tear strength, abrasion resistance and etc. can be significantly improved. Permanent deformation can be reduced, and meanwhile it can reduce the compound viscosity and improve processing performance. It is suitable for polymers like natural rubber (NR), isoprene rubber (IR), styrene-butadiene rubber (SBR), butadiene rubber (BR), nitrile rubber (NBR), ethylene-propylene-diene rubber (EPDM), etc.
