High Jetness / Pigment Black 7
Carbon Black is a form of elemental carbon manufactured by the controlled vapor-phase pyrolysis of hydrocarbons. It is the most widely used black pigment in the world, prized for its high Tinting Strength (covering power), UV stability, and electrical conductivity. We offer specialty grades for Coatings (High Jetness) and Rubber (Reinforcement).
Carbon Black is not just a black powder; it is an engineered nanomaterial. Its properties are defined by particle size, structure (aggregate size), and surface chemistry. We supply both Specialty Blacks (for Inks/Plastics) and Industrial Blacks (for Rubber).
Comparison of key parameters for High Color (Coating) and Industrial (Rubber) grades.
| Parameter | High Jetness (Coating/Ink) | N330 (General Rubber) |
|---|---|---|
| Particle Size (nm) | 10 - 25 nm (Very Fine) | 26 - 30 nm |
| BET Surface Area ($m^2/g$) | 200 - 300 $m^2/g$ | 75 - 85 $m^2/g$ |
| DBP Absorption (Structure) | 95 - 105 ml/100g | 100 - 105 ml/100g |
| Tinting Strength | 120% - 140% | 100% - 105% |
| pH Value | 2.5 - 4.5 (Acidic/Oxidized) | 7.0 - 9.0 (Alkaline) |
| Volatile Matter (950°C) | 1.5% - 5.0% | Max 1.0% |
The "blackness" or Jetness of Carbon Black depends entirely on its primary particle size.
Used in offset inks, flexographic inks, and laser printer toners for deep black printing.
High Color blacks used for basecoats to achieve the "Piano Black" finish.
Used for coloring films, pipes, and cables. Provides critical UV protection for outdoor plastics.
Reinforcing filler that improves wear resistance and durability of tires and belts.
Conductive grade (Acetylene Black) is used in dry cell and Lithium-ion batteries.
Used for coating synthetic leather and shoe soles.
Multi-layer kraft bags. Because Carbon Black is extremely light (low bulk density), bags are large.
Big bags for automated industrial feeding systems.
Carbon Black is generally non-toxic but is a nuisance dust.
