For procurement managers and R&D scientists in the chemical industry, a thorough understanding of product specifications is essential for making informed purchasing decisions. N660 Carbon Black is a widely used industrial chemical, particularly in rubber and plastics, and knowing its key technical parameters is crucial for application success. This guide provides an overview of N660 Carbon Black's technical specifications and offers insights on how to procure it from a reliable manufacturer like NINGBO INNO PHARMCHEM.

Key Technical Specifications of N660 Carbon Black

The performance of carbon black is dictated by several physical and chemical properties. For N660 grade, the following specifications are particularly important:

• Iodine Adsorption Number: This measures the surface area of the carbon black particles accessible to iodine molecules. For N660, a typical range is 36 ± 4 g/kg (Superior grade) or 36 ± 6 g/kg (Qualified grade) as per ASTM standards. A higher iodine number generally indicates a higher surface area and greater reinforcing potential.
• DBP Absorption Number: This indicates the oil absorption capacity, reflecting the structure and particle size of the carbon black. For N660, the typical DBP Absorption Number is 90 ± 5 (10⁻⁵ m³/kg) for the Superior grade and 90 ± 7 for the Qualified grade. This property influences the compound viscosity and processing.
• Compressed DBP Absorption Number: This is a measure of oil absorption under pressure, providing further insight into the structure. For N660, it typically ranges from 69 to 79 (10⁻⁵ m³/kg) for the Superior grade and 66 to 82 for the Qualified grade.
• CTAB Surface Area: The Cetyl Trimethyl Ammonium Bromide (CTAB) surface area is another metric for particle fineness. For N660, it generally falls between 31-41 (10³ m²/kg) for the Superior grade and 29-43 for the Qualified grade.
• Nitrogen Surface Area: Similar to CTAB, this measures the surface area accessible to nitrogen molecules, providing a comprehensive understanding of the particle surface. For N660, typical values are 31-39 (10³ m²/kg) for the Superior grade and 29-41 for the Qualified grade.
• PH Value: Typically around 7 ± 1.5, indicating a near-neutral pH.
• Heating Loss: Usually not more than 1.5%, indicating low volatile content.
• Ash Content: Generally not exceeding 0.7%, signifying high purity.

These specifications, often detailed in a Technical Data Sheet (TDS), are critical for formulators to predict how the carbon black will behave in their specific matrix and achieve the desired end-product properties.
