For Research & Development scientists and product formulators in the rubber industry, understanding the precise technical specifications of raw materials like Carbon Black N330 is critical for successful product development and optimization. NINGBO INNO PHARMCHEM CO.,LTD., a leading manufacturer and supplier of Carbon Black from China, provides transparent access to the detailed properties that make N330 a superior choice for various rubber applications.

Carbon Black N330, classified as a High Abrasion Furnace (HAF) grade, is distinguished by its unique combination of particle size, surface area, and structure. These physical attributes directly translate into its performance characteristics when incorporated into rubber compounds, influencing everything from abrasion resistance to tensile strength.

Key Technical Parameters of Carbon Black N330:

When considering the purchase of Carbon Black N330, paying close attention to the following specifications is vital:

  • Iodine Absorption Value (g/kg): This parameter measures the surface area of the carbon black particles. For N330, the typical range is around 77-87 g/kg (superior) or 82±7 g/kg (qualified). A higher iodine number generally correlates with a finer particle size and greater reinforcing capability.
  • DBP Absorption Value (10⁻⁵m³/kg): Dibutyl Phthalate (DBP) absorption is an indicator of the carbon black's structure or particle agglomeration. N330 usually falls within the range of 97-107 (qualified) or 102±7 (superior). Higher DBP absorption suggests a more branched structure, which can improve processing and reinforcement.
  • Compressed DBP Absorption Value (10⁻⁵m³/kg): This measurement provides insight into the structure of the carbon black after it has been subjected to pressure. For N330, this value typically ranges from 80-96 (qualified) or 83-93 (superior).
  • CTAB Surface Area (10³m²/kg): Cetyl Trimethyl Ammonium Bromide (CTAB) absorption is another measure of external surface area. N330 usually has a CTAB surface area in the range of 77-87 (superior) or 73-91 (qualified).
  • Nitrogen Surface Area (10³m²/kg): This value indicates the total surface area, including internal pores. For N330, it typically falls between 78-88 (superior) or 71-85 (qualified).
  • Tinting Strength (%): This refers to the pigmenting capability of the carbon black. N330 generally offers a tinting strength of 96-112%.
  • Heating Loss (%): A measure of volatile matter, typically less than 2.5% for N330.
  • Ash Content (%): Indicates the level of inorganic impurities, usually less than 0.5% or 0.7% for N330.
  • 300% Modulus (MPa): This measures the stiffness of the rubber compound after being stretched to 300% elongation. For N330, it's typically around -0.5 to -1.5 MPa.

These technical specifications are crucial for formulators to predict how the carbon black will behave in their rubber compounds and to achieve the desired performance characteristics, such as optimal abrasion resistance for tire treads or enhanced tensile strength for industrial rubber products.
