Product N330 detailed introduction:(price:1397$/T)
1. Physical and chemical properties: Gaoxin Zhongcai Brand N330 is the most widely used high wear-resistant carbon black. Its wear resistance is slightly worse than that of the Zhongchao wear-resistant series carbon black, but better than that of the slot method carbon black.
2. Usage: Used for tire tread, cord rubber, tire sidewalls, and various rubber industrial products, silicone, plastic, grinding wheel, shoe material, leather, asbestos tile defoaming, wire and cable, color masterbatch, and other industries.
3. Usage and Function: This product is a carbon black with good reinforcement performance, which can endow rubber and other materials with good strength, elongation, tear resistance, wear resistance, and elasticity. It also has good wear resistance and moderate hysteresis. The rolling loss (hysteresis loss) of passenger tires using this product is only greater than N351 in the N300 series, which is smaller than other varieties. It also has good dispersion and extrusion performance in rubber materials and is suitable for various synthetic rubber, natural rubber, and other places that require wear resistance.

Product N220 detailed introduction:(price1506$/T)
1. Physical and chemical properties: This product is a widely used high reinforcement furnace type carbon black, with a high structural type, and its wear resistance is between super wear-resistant and high wear-resistant carbon black.
2. Usage: Used for tread rubber for heavy-duty tires, passenger car tires, and rubber products that require high strength and wear resistance, such as high-strength conveyor belts and industrial rubber products.
3. Product characteristics: This product is suitable for various rubber products. Compared with N330, the wear resistance of carbon black rubber containing N220 is 10% -20% higher, which can endow the rubber with higher tensile strength and certain conductivity, but with higher heat generation and hardness.
