Carbon Black N339 is recommended to be used in the tread rubber for ordinary car tires, heavy lorry tires. As well as the covering rubber of conveyer belt, the rubber tubes, and the rubber products requires for high wear resistance.
N339 has nearly the same reinforcing intensity, wear resistance, and tear resistance as N220. It is well extrusion, especially fits for Styrene Butadiene Rubber (SBR) and Cis-Polybutadiene Rubber.
