Understanding the Principles and Selection of Conductive Carbon Black

The fundamental principle of conductive carbon black lies in the distance and quantity of carbon particles within carbon black agglomerates (clusters formed by multiple aggregates), which determine the conductivity of rubber compounds. This is analogous to how thicker wires provide better electrical conductivity in metals. To select the right conductive carbon black, consider the following factors:

1. Oil Absorption Value (Structure): High-structure carbon black exhibits superior conductivity.
2. Ash, Impurities, and Sieve Residue: Reducing non-carbon content increases the effective proportion of carbon black in rubber compounds.
3. Particle Size: Typically 20-40nm, with most conductive carbon blacks falling within this range.
4. Low Volatile Content: Fewer surface oxygen groups, resulting in a neutral carbon black.
5. Low Solvent Extracts: Prevents the formation of insulating layers.
6. High Iodine Absorption: Hollow-shell carbon blacks are preferable.
7. Uniform Dispersion: Ensures effective utilization of carbon black's conductive properties.
8. Post-Heat Treatment: Enhances overall performance.
9. Maximize Loading: Subject to cost constraints and rubber compound performance.
