  • Carboxyethylated lignosulfonate

    Carboxyethylated Lignosulfonate

    It is an anionic and water soluble material. Its charge density and molecular weight are in the ranges of -2.7~ -3.5 meq/g and 32000 ~ 47900 g/mol, respectively. This material can be potentially applied in mining and oil as well as water based dispersion systems, as dispersant of industrial wastewaters and clay suspensions for instance.

  • Oxidized kraft lignin-1

    Oxidized kraft lignin-1

    Oxidized kraft lignin 1 is a water soluble low molecular weight (15000 g/mol), highly functionalized anionic (charge density of -2.2 meq/g) lignin-based macromolecules. This lignin-based organic polymer can be used as dispersant of industrial wastewaters and clay suspensions.

  • Oxidized kraft lignin-2

    Oxidized kraft lignin-2

    Oxidized kraft lignin-2 is an anionic lignin-based low molecular weight materials. Its charge density and molecular weight are in the ranges of -1.2~ -3.6 meq/g and 11600 ~ 83500 g/mol, respectively. This lignin-based organic polymer can be used as dispersant of industrial wastewaters and clay suspensions.
