Specific use
1. reinforcing agent and filler for rubber products
2. usage and function: the reinforcement, wear resistance and tear resistance of this product in tread compound are close to N220 carbon black, and the extrusion performance is also good. It is especially suitable for SBR / cis-1,4-polybutadiene rubber blend system. However, when using this product to produce tread compound, its rolling resistance is the highest among N330 series carbon black, which should be paid attention to in the formulation design of the compound.
