Affect the nature of the black plastic into the following three characteristics:
First, from the blackness and the particle size, the blackness directly associated with the carbon black pigment particle size, particle size, the higher the degree of pigment carbon black. This is because, although the primary particle has fused native aggregates, but it can still work surface area, the finer the primary particle, the larger the surface area of the body of its cohesion.
Second, the structure, the carbon black particles not only to the formation of primary particles exist, and in the production process often melt to form aggregates. This aggregate is a former student of particles through chemical bond. Carbon black structure also affects the ease of dispersion, for example, high density and aggregate accumulation tightness low structure carbon black, Pigment Carbon Black structure is high and the average distance between each other which is smaller aggregates.
Finally, the surface chemistry, various methods of production, the surface chemical properties different.
