Reactive black and dispersed black are two common pigments that have wide applications in various industries. Although they have similar names, they actually have significant differences in nature and use

The preparation methods of active black and dispersed black are different. Active black is obtained by inserting atoms or molecules onto the surface of pigments, forming active centers that react with other substances. And dispersed black is obtained by dispersing pigments in solvents or resins

There are also differences in the physical and chemical properties between the two. Activated black pigment has high moisture absorption and hydrophilicity, and its surface is prone to react with gases, liquids, or other pigments. The molecular structure of dispersed black is relatively stable and not easily affected by external conditions

In terms of application, active black and dispersed black also have different uses. Due to its strong reactivity with other substances, active black pigments are commonly used in industries such as rubber, ink, and adhesives. It can increase the adhesion between pigments and substrates, improve the adhesion and durability of products. And dispersed black is mainly used in fields such as plastics, coatings, textiles, etc. Dispersed black pigment particles are small, have good dispersibility, can evenly color, and bring good coverage and color to the product

In addition, there is also a price difference between the two. Due to the complex preparation process of active black pigment and the high requirements for raw materials, its price is relatively high. Due to its simple preparation process and common raw materials, dispersed black has a relatively low price

In summary, although the names of active black and dispersed black are similar, there are significant differences in preparation methods, physical properties, chemical properties, application fields, and prices. For different industries, it is very important to choose suitable pigments based on the specific requirements of the product. I hope this article can help readers better understand the difference between active black and dispersed black, and provide reference for selecting appropriate pigments.
