Grade and Particle Size: Different grades of Carbon Black, including N220, N330, N339, N440, N550, N660, and N990, provide unique reinforcing properties that cater to diverse industrial needs. Particle size and surface area impact each grade’s specific application and performance characteristics.

Quality Control: Rigorous testing is conducted on each batch of Carbon Black to ensure it meets industry standards. We assess key parameters like particle size, structure, surface area, and tint strength to guarantee performance and consistency in each application.

Carbon Black Grades and Applications:

N220: High abrasion resistance makes it ideal for applications requiring maximum durability, such as tire treads, conveyor belts, and mechanical goods.
N330: Known for its general-purpose reinforcement properties, N330 is widely used in industrial rubber products, offering a balance of strength and resilience.
N339: With superior reinforcing abilities, this grade is suited for heavy-duty rubber goods, offering enhanced toughness and durability.
N440: Provides moderate tensile strength and flexibility, making it suitable for rubber extrusions and applications where balance between durability and flexibility is needed.
N550: Easier to disperse due to its lower surface area, N550 is favored in softer rubber compounds, especially for automotive components and mechanical goods.
N660: Known for its lower reinforcement levels, N660 is suited for products requiring high flexibility and elongation, such as inner tubes and soft rubber parts.
N990: A Thermal Black with large particle size, N990 provides low reinforcement, making it ideal for specialty applications like gaskets, seals, and low-durability rubber parts.
