carbon black - pigment dispersion

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, in order 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.

ISO 18553 method provides procedures for assessing the degree of dispersion by physical measurement of the size of the dispersed particles (carbon black or color pigments) and arithmetically grading the particle size distribution. It also provides photographs for comparison with microscopic images of samples taken from raw-material compound or products in order to judge subjectively, the acceptability of carbon black or pigment dispersion

why impact?

Some members of impact’s team have over 30 years of polymer experience, with over 120 years combined, and are internationally regarded as product experts including sitting on various CEN committees and being a notified body for construction products (Note because of our notified body status we cannot undertake consultancy on oil storage tanks), we can often identify potential sources of weakness in products without even undertaken testing using our experience.
