Pigment carbon black used in plastics industry

 Pigment carbon black used in plastics industry

 
The carbon black pigment can generally better for coloring plastics, can be selected according to the properties of carbon black pigment coloring property or material, color black varieties selection basically is with the product must meet the blackness and. Use of pigment ultrafine carbon black can complete blackness requirements are particularly high coloring; PE garbage bags, plastic bags, products such as the cable material only moderate density, can be used to lower the specific surface area, carbon black structure high; plastic color, small error of weighing and batching of carbon black, will lead to obvious color difference, therefore, should adopt the larger particle size, low carbon black pigment coloring ability, this amount of carbon black can be slightly larger, the weighing error is relatively small, and has advantages of good dispersion, low price.
For the gray plastic, with fine pigment carbon black tends to Brown is grey, and the coarse particles of carbon black pigment can produce blue grey.
Compared with other organic pigment carbon black dispersion is difficult, in addition to outside, other properties are good. The amount of carbon black with science, can provide good antistatic or conductive.
Carbon black is basically harmless, but easy to dust and pollution, so often in Masterbatch form for use in the plastics industry, eliminate pollution but also improve the dispersion of carbon black in plastics.
Black as the plastic pigments, commonly used forms of powder and granular. Granular carbon black dust less, but the dispersion is more difficult, so the use of powdered carbon black in plastics coloring in.
