Molecular Structure:

Product description: White carbon black(SiO2) is designed to improve dispersibility,absorption,abrasion or transpareny.The main markets are the tire industry,rubber soles,and feedstuff.Silica with special physic-chemical properties,work as reinforcing transparent fillers highly valued in formulation of rubber-based blends.They can lead to enhanced tensile strength,tear strengh and abrasion resistance and increase hardness of vulanised rubbers. White carbon black(SiO2) is reinforcing filler for rubber soles with high reinforcing effect as that of carbon black,and it can make rubber product with light color or transmissivity.
