Factory provide silica hydrated 98% food grade

 

1) MF:SiO2 nH20
2) white powder or granular

3) 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.
