2. Application
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.
Main used in high grade rubber , tyre ,soles and pesticide, feedstuff additive industry.
