Precipitated Silica 231-545-4

Basic Info

Model No.: Precipitated Silica 231-545-4

Product Description

Precipitated Silica 1.Specification Precipitated silica with special physic-chemical properties, works as reinforcing transparent fillers highly valued in formulation of rubber-based blends. In particular, it leads to enhanced tensile strength, tear strength and abrasion resistance and increase hardness of vulcanized rubbers. On the other hand, it reduces consumption of rubbers and therefore reduces the cost. 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.
