Carbon Black Dispersion

Carbon black (graphite) is one of the most popular plastic additives not only because it is a cheap source of black pigment but also because it offers excellent mechanical properties and resistance to oxidation-weathering. However, for carbon black to be functional, it needs to be dispersed properly within the plastics.

Large agglomerates of carbon black can cause the opposite of the desired results, especially in pipe materials. Therefore, assessing the degree of carbon black dispersion is important.

The equipment provides assessing the degree of dispersion by physical measurement of the size of the dispersed particles (carbon black or colour pigments) and arithmetically grading the particle size distribution.

It provides live particle size measurement using our test software to judge subjectively, the acceptability of carbon black or pigment dispersion.
