Carbon Black N326 High Performance Powder for Rubber Industry
Material Overview
Carbon black represents a critical engineered material in modern industry, characterized by its unique combination of optical, electrical, and mechanical enhancement properties. This amorphous carbonaceous powder, produced through controlled pyrolysis of hydrocarbons, serves dual functions as both a premier black pigment and a performance-enhancing filler. With its exceptionally fine particle size (15-300nm) and high surface area (25-1500 m²/g), carbon black delivers unparalleled functionality across rubber, coatings, plastics, and specialty chemical formulations.
Key Technical Specifications
Physical Characteristics
- Particle Structure: Complex fractal aggregates with 1.8-2.1 g/cm³ apparent density
- Surface Chemistry: Oxygen-containing functional groups (0.1-5.0% volatile content)
- Morphology: Spherical primary particles (10-80nm) forming chain-like aggregates
- Electrical Properties: 0.1-100 Ω·cm resistivity (tailorable for conductive grades)
Performance Parameters
- Tinting Strength: 100-300% relative to standard channel blacks
- Oil Absorption: 65-300 ml/100g (DBP absorption method)
- pH Value: 2.5-11.0 (surface treatment dependent)
- Thermal Stability: Maintains integrity up to 400°C in inert atmospheres
Manufacturing Process
Produced through advanced furnace black technology, our carbon black undergoes precise thermal decomposition of heavy aromatic oils at 1200-1600°C under oxygen-limited conditions. This controlled process enables:
- Structure Control: Adjustable aggregate size (10-500nm) through reactor kinetics
- Surface Modification: In-situ creation of carboxyl/hydroxyl groups for enhanced compatibility
- Grade Differentiation: Tailored iodine adsorption numbers (30-180 g/kg) for specific applications
