It has stronger appetency, which make it effect greater disperse ability. The phisical character effected by the partical of white carbon and molecule of rubber is better than that of carbon in the aspect of inhance vulcanized rubber&#**9;s machanical intensity and tear enhancing. Applying: tyre, translucence or high clarity rubber products and rubber sole etc.
