What Is Carbon Black N339?

Carbon Black N339 serves as a widely used, high-performance reinforcing filler, and manufacturers primarily design it for tire tread and rubber products. Because it offers an excellent balance between hardness and elasticity, it supports products that need both durability and flexibility. While manufacturers mainly use it in rubber compounding, they also apply it in plastics and other polymer-based materials.

Since it belongs to the hard-grade family, industries favor N339 for its high abrasion resistance. In addition, its good dispersion properties allow producers to maintain consistent performance throughout the production process. Therefore, many companies consider N339 one of the most versatile and in-demand grades available on the market.

Why Choose Carbon Black N339?

Carbon Black N339 is known for providing:

  • High abrasion resistance: Ideal for long lasting rubber components

  • Excellent reinforcement: Improves tensile strength and elasticity

  • Fast processing: Ensures smooth mixing and easy dispersion

  • Low hysteresis: Reduces rolling resistance in tires

  • Versatile application: Works in tires, belts, hoses, and molded goods

Because of these characteristics, it is widely adopted by manufacturers who need superior mechanical strength without sacrificing flexibility.

Main Applications

Although it’s often associated with tire treads, CarbonBlack N339 is used in several industries:

  • Tires: Tread compounds for enhanced wear resistance

  • Belts and Hoses: Reinforced structure and tensile strength

  • Rubber Molding: Durable seals, gaskets, and vibration damping parts

  • Plastics: Conductive and anti static properties

  • Industrial Rollers: Improved surface wear characteristics

  • Footwear Soles: Excellent flexibility with high durability

As a result, this grade plays a critical role in high-performance applications where long life and structural stability are essential.

How Carbon Black N339 Compares to Other Grades

Compared to other hard grade furnace blacks, N339 offers:

  • Better processing than N220

  • Higher wear resistance than N330

  • More tensile strength than N660

  • Balanced reinforcement and flexibility

Consequently, it stands out in applications that require both strength and consistent quality.

Packaging & Storage

The product is available in:

  • 20–25 kg paper or PE bags

  • Jumbo bags (500–1000 kg) with liner

  • Custom packaging on request

Therefore, it should be stored in a dry, covered area, away from direct sunlight. In fact, proper storage extends product shelf life and maintains performance.
