General description: 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.
