Carbon Black N330 is a staple in many industrial manufacturing processes, prized for its balance of performance, versatility, and cost-effectiveness. As a critical raw material, understanding its specifications and optimal sourcing strategies is vital for any business relying on this compound. NINGBO INNO PHARMCHEM CO.,LTD., a leading chemical manufacturer and supplier, provides a comprehensive overview of Carbon Black N330 to assist procurement managers, R&D scientists, and formulators.

The performance of carbon black is largely dictated by its physical and chemical properties, including particle size, surface area, structure, and surface chemistry. These properties influence its reinforcing capabilities, pigmentary strength, and processing behavior. When you choose to buy Carbon Black N330, you are selecting a material engineered for specific industrial demands.

Key Specifications of Carbon Black N330

The ASTM (American Society for Testing and Materials) standard D1524 classifies carbon blacks by performance characteristics, with the N-series denoting channel and furnace blacks. Carbon Black N330 falls into this category and is defined by several key specifications that dictate its suitability for various applications:

  • Iodine Absorption Number (g/kg): Typically around 82 ± 5 g/kg. This indicates the surface area accessible to large molecules and relates to the compound's reinforcing capabilities. Higher iodine numbers generally suggest smaller particle sizes and greater surface area.
  • DBP Absorption Number (10⁻⁵ m³/kg): For N330, this is usually 102 ± 5 (10⁻⁵ m³/kg). This value reflects the structure of the carbon black aggregates – how they are linked together. Higher DBP absorption indicates a more branched, clustered structure, which can improve rubber processing and modulus.
  • CTAB Surface Area (10³ m²/kg): A typical range for N330 is 79-87 10³ m²/g. This is a measure of the external surface area of the carbon black particles.
  • Nitrogen Surface Area (10³ m²/kg): Similar to CTAB, this is also in the range of 78-88 10³ m²/g, reflecting the fine nature of the particles.
  • Tint Strength: N330 offers a tinting strength that is generally lower than finer grades (e.g., N220), but still provides good opacity and color intensity for most applications.
  • Heating Loss (%): Usually ≤ 2.5%. This indicates the presence of volatile surface groups.
  • Ash (%): Typically ≤ 0.5%. A low ash content signifies high purity.

Applications of Carbon Black N330

The balanced properties of N330 make it highly versatile:

  • Rubber Industry: Primarily used in tire treads, sidewalls, and various industrial rubber products where a good balance of abrasion resistance, tensile strength, and cost is needed. It's also employed in hoses, belts, and seals.
  • Plastics and Masterbatches: As a pigment, N330 provides deep black coloration, opacity, and UV protection in plastics. It is commonly used in masterbatches for injection molding, extrusion, and film applications.
  • Coatings and Inks: In paints, coatings, and printing inks, N330 acts as a pigment to achieve black hues, offering good dispersion and tinting strength.

Sourcing Carbon Black N330 Effectively

To source Carbon Black N330 effectively, consider the following:

  • Supplier Reputation: Partner with established manufacturers and suppliers who can provide consistent quality and reliable delivery.
  • Technical Support: A good supplier will offer technical support to help you select the right grade and optimize its use in your formulations.
  • Competitive Pricing: While quality is paramount, competitive pricing is also essential. Direct sourcing from manufacturers often provides better value.
  • Logistics and Packaging: Ensure the supplier offers suitable packaging (e.g., 20/25 kg bags) and can manage international logistics efficiently.
