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.
