Applications:
Si69C is the mixture of Bis[γ-(triethoxysilyl)propyl]tetrasulfide and carbon black, owns the same effects of Si69, but it is easier to use. It can greatly improve physical and mechanical properties, tensile strength, tear strength, abrasion resistance of rubber, and lower the permanent deformation and viscosity of rubber materials, and improve processing performance. It is suitable for the rubber vulcanization system taking white carbon black or silicate as the reinforcing agent, usable fillers include silica, talc, clay, mica, clay, etc., and suitable polymers include NR, IR, SBR, BR, NBR, EPDM etc.
