1. Compared with other pigments, carbon black has better coloring power and covering power.
2. Compared with other pigments, carbon black has excellent heat resistance, chemical resistance and light resistance.
3. As a result of the carbon black particle size is only several nanometer to dozens of nanometer, porosity of 90%, and inorganic materials, general carbon black is therefore difficult to steady dispersed into the organic resin system, and strict control and the production of special modified carbon black pigment can very good in coating, ink and plastic system reflect dispersion.
4. Compared with rubber carbon black, pigment carbon black has more and more special requirements for such quality indexes as blackness, pigmentation, surface activity, conductivity, ash content, toluene transmittance, dispersion and fluidity.
