Overview
Dispersible High Color Carbon Black is a premium-grade pigment derived from the incomplete combustion of hydrocarbons. It is engineered for superior dispersibility in various matrices, making it a preferred choice for high-performance applications. Unlike conventional carbon black, this variant undergoes surface treatment to reduce agglomeration, ensuring uniform distribution in formulations. Its primary advantage lies in its high tinting strength, which allows for deep, stable coloration with minimal additive quantities. This property is critical in industries requiring consistent color quality, such as automotive coatings and packaging inks.
Physical and Chemical Properties
This carbon black exhibits a fine particulate structure with a surface area typically ranging from 100-300 m²/g, contributing to its high adsorption capacity. Its chemical inertness makes it resistant to acids, alkalis, and solvents, ensuring stability in harsh environments. Key physical metrics include a bulk density of 0.2-0.5 g/cm³ and a primary particle size of 10-30 nm. The material is non-flammable but may form explosive dust-air mixtures if improperly handled. Its UV resistance makes it suitable for outdoor applications like solar panels and construction materials.
Main Applications
In the ink industry, this carbon black is used in jet inks, toners, and gravure printing due to its jetness and rheological properties. Coatings formulations leverage its UV stability for automotive finishes and industrial protective layers. Plastics and rubber industries incorporate it for conductive applications (e.g., anti-static packaging) and tire manufacturing. Emerging uses include lithium-ion battery electrodes and specialty ceramics, where its conductivity and purity are advantageous.
Safety and Storage
While non-toxic, prolonged exposure to airborne particles may cause respiratory irritation. NIOSH-approved dust masks and local exhaust ventilation are recommended during handling. Storage should avoid moisture to prevent caking. Containers must be grounded during transfer to prevent static discharge. Spills should be cleaned with vacuum systems rather than brooms to minimize dust generation. Compatibility testing is advised when combining with oxidizers or strong acids.
B2B Procurement Guide
Buyers should prioritize suppliers who provide technical datasheets with metrics like DBP absorption (110-150 ml/100g) and volatile content (<2%). Batch-to-batch consistency is critical for color-sensitive applications. Consider ordering samples for dispersion testing in your specific formulation. Bulk purchases (20+ metric tons) often attract discounts of 10-15%. Logistics should account for its classification as a non-hazardous material (UN1361, PG III).
