Silicon Dioxide / Precipitated Silicon Dioxide / White Carbon Black Used For Rubber, tyre ,Soles and Pesticide
General description of silicon dioxide
Precipitated silica with special physic-chemical properties, work as reinforcing transparent fillers highly valued in formulation of rubber-based blends. In particular, They lead to enhanced tensile strength, tear strength and abrasion resistance and increase hardness of vulcanized rubbers. On the other hand, They reduce consumption of rubbers and therefore reduce the cost.

Feature
It has stronger appetency, makes it bear biggish dispersive ability in fresh rubber, physical appearance comes into being that white carbon black grain and rubber molecule, excelled white carbon black in boosting up mechanical strength of rubber and reinforcement of tear. It is highly reinforcing agent of rubber.
Application
Main used in high grade rubber , tyre ,soles and pesticide, feedstuff additive industry.
