Silane coupling agent SI69C 1333 86 4

Characterization and application:

Si69C is the mixture of 50% Si69 and 50% N330 carbon black. The operation process will be more convenient by using Si69C, while the equivalent efficacy can be gained as using Si69. It can be used to increase the compatibility between rubber and fillers, to improve the reinforcing effect of fillers, and to reduce the hysteresis loss. Thus the mechanical properties, as well as compression heat, wear and permanent deformation performance of vulcanizate can be ameliorated significantly. By using Si69C, the adverse effects of fillers on curing rate and crosslinking degree can be eliminated and the mooney viscosity of rubber compound can be reduced, as a result, the manufacturing process can be improved significantly. Meanwhile, the cure reversion phenomenon, to some extent, can also be relieved.
