For manufacturers working with rubber, plastics, coatings, and inks, understanding the precise specifications of their raw materials is crucial for achieving optimal product performance and consistency. Carbon Black N330, a widely used grade, has a set of key technical parameters that dictate its behavior and effectiveness. NINGBO INNO PHARMCHEM CO.,LTD, as a reliable supplier, emphasizes the importance of these specifications for its customers.

One of the most critical specifications for Carbon Black N330 is the Iodine Absorption Value. This value, typically measured in grams per kilogram (g/kg), indicates the surface area of the carbon black particles. For N330, a common range is around 82 ± 7 g/kg. A higher iodine absorption value generally correlates with a smaller particle size and a larger surface area, which in turn can lead to higher reinforcement, better UV protection, and increased conductivity. Manufacturers often select grades based on the required surface area for their specific application.

Another vital parameter is the DBP (Dibutyl Phthalate) Absorption Value. This measurement, usually expressed in cm³/100g, reflects the structure or aggregate size of the carbon black. A higher DBP absorption value suggests a more complex, branched structure, which can lead to higher viscosity, improved electrical conductivity, and easier dispersion in polymer matrices. For N330, the DBP absorption is typically around 102 cm³/100g. This characteristic is essential for rubber compounders to achieve the desired processability and final mechanical properties.

The Tint Strength of Carbon Black N330 is also an important indicator, particularly when it's used as a pigment. It quantifies the carbon black's ability to impart color to a white pigment mixture. A higher tint strength means less carbon black is needed to achieve a desired blackness, offering economic advantages. While specific values can vary slightly, N330 generally exhibits a tint strength that balances pigmentation with its reinforcing role.

Furthermore, specifications related to particle size, ash content, and sieve residue are important for quality control. Ash content, for instance, should be kept to a minimum (e.g., ≤ 0.5%) to ensure the purity of the carbon black. Sieve residue, particularly for particles larger than 45μm or 150μm, should be very low (e.g., ≤ 0.100%) to prevent processing issues and ensure a smooth final product. These parameters, along with others like heating loss and tensile strength of rubber compounds, are meticulously controlled by reputable suppliers like NINGBO INNO PHARMCHEM CO.,LTD.

For manufacturers looking to buy Carbon Black N330, consulting detailed product specification sheets is essential. These documents provide the precise ranges for all critical parameters. NINGBO INNO PHARMCHEM CO.,LTD is dedicated to providing transparent and accurate technical data, enabling customers to make informed decisions. By understanding and utilizing these specifications, manufacturers can effectively leverage the full potential of Carbon Black N330 to achieve superior product performance and consistency in their tire, rubber, plastic, and coating applications.
