1. Compared to other pigments, carbon black has better tinting strength and hiding power.
2. Compared with other pigments, carbon black has excellent heat resistance, chemical resistance and light resistance.
3. Since the carbon black has a particle size of only a few nanometers to several tens of nanometers, a porosity of 90%, and an inorganic material, ordinary carbon black is difficult to stably disperse into an organic resin system, and is strictly controlled and The pigmented carbon black produced by the special modification process can well disperse in the coating, ink and plastic systems.
4. Compared with rubber carbon black, pigment carbon black has more and more special requirements for quality indicators such as blackness, tinting strength, surface activity, electrical conductivity, ash, toluene transmittance, dispersibility and fluidity.
