1. Features: Mainly used in riding tires, the truck tire tread rubber, rubber covered conveyor belt, hose and high wear resistance of the various requirements of industrial rubber products.

2. Usage and Role: This product is used as tread reinforcement, which wear and tear properties are similar to N220, squeeze performance better, especially for styrene-butadiene rubber, cis-butadiene rubber. When N339 is used as tread in rubber production, the rolling resistance is the highest in the N330 series carbon black, which more attention must be given in the rubber formulation.
