The binding properties of StarLig products are widely used in pelleting finely dispersed powders. In mineral and carbon black granulation, producers can obtain compact and uniform sized granules that are crush-resistant. Suspensions of carbon black behave as semi-solids, even at low concentrations. Using StarLig products reduces viscosity and therefore facilitates processing of the material.
Sodium lignosulfonate or magnesium lignosulfonate are most commonly used for this purpose. Depending on the technical requirements, also high-end ammonium lignosulfonate or purified premium StarLig lignosulfonates can be applied. This gives a direct positive impulse to the process sustainability and efficiency in carbon black granulation.
