carbon black for plastics usually requires strong tinting strength, high impurity, and fine dispersion.
 
carbon black of low structure, small particle size is  usually used in these fields which need high tinting strength, high gloss.
 
carbon black of high structure ,large particle size is usually used in color combinaton, Such area which needs fine dispersion performance.
