Pigment Carbon Black

Pigment carbon black, known for its superior tinting strength compared to iron black or organic pigments, also offers excellent thermal stability. As a result, it is widely used as a colorant in various applications, including printing inks, paints, coatings, plastics, textile printing and others.

² Characteristics of pigment carbon black:

1. Comparing with other pigment, carbon black is better in tinting strength and hiding power.

2. Comparing with other pigment, carbon black is good in durability on heat, chemicals and light.

3. Carbon black is difficult to disperse stably in the organic resin system because its particle size only ranges from a few nanometers to dozens of nanometers, and porosity reaches 90%, moreover, it is inorganic materials. However, carbon black after strict control and treated with special craft can be well dispersed in paints, inks and plastic system.

4. Comparing with rubber carbon black, pigment carbon black has higher and more specific requirements in blackness,tinting strength,surface activity,conductivity,ash,light transmittance of toluene,dispersibility,fluidity and other technical indexes.

² Powder Form and Bead Form of Carbon Black

Pigment carbon black has two physical existing forms: powder form and bead form. Powder form is easy to disperse but with high transport cost and is apt to cause environmental pollution while using. Bead form is convenient to transport due to low dust pollution and high density, but is difficult to disperse by comparison with powder form.
