High wear resistant carbon black, wear resistance of this product somewhat less than the super-resistant series of carbon black, but black is better than cell method. For tire tread, cord fabric rubber, sidewall rubber and industrial products. This product is a good reinforcement properties of carbon black, rubber to give better tensile properties, tear resistance, abrasion resistance and flexibility. The FDA's passenger tire rolling losses ( hysteresis loss ) series of carbon black only in N300 than N351, than the other varieties are small, dispersed in the rubber compound and extrusion performance is also good for kinds of synthetic rubber and natural rubber.
