PRECIPITATED SILICA for rubber, shoe

PRECIPITATED SILICA for rubber, shoe
Product Detailed
PRECIPITATED SILICA for rubber, shoe SiO2 nH2O white powder/granular competitive price  PRECIPITATED SILICA for rubber, shoe1) MF:SiO2 nH202) white powder or granular3) Grade:industrial grade

 properties:

With special physic-chemical properties, Precipitated silica work as reinforcing transparent fillers highly valued in formulation of rubber-based blends, lead to enhanced tensile strength, tear strength and abrasion resistance and increase hardness of vulcanized rubbers, reduce consumption of rubbers and therefore reduce the cost.
