Sodium lignosulfonate is a kind of inorganic, chemical formula for C20H24Na2O10S2, lignin is only second to the content of cellulose and chitin natural polymer in nature, one of its most widely used is through sulfonation modification into lignosulfonate. Lignininsulfonate of sodium is one of them. Sodium lignosulfonate can be used as an admixture for polymers and concrete, and has the advantages of low cost and environmental friendliness. It's a custom cas no 8061-51-6 sodium lignosulfonate product, feel free to contact us!

Main Performance of Sodium Lignosulfonate(SF-3)


  • It can be used as a general water reducer and a series of multifunctional building materials with high performance water reducer.

  • It can be used as a binder in the briquetting process of vertical cooking zinc smelters.

  • It can be used as a blank reinforcing agent in the field of ceramics and refractory materials. They increase the fluidity of the slurry and thus the strength of the embryo.

  • Sodium lignosulfonate series products can be used as the main composite material in the field of coal water slurry.

  • In agriculture, sodium lignosulfonate series products can be used as dispersants for pesticides.

  • Granulation binder for pesticides, fertilizers and feed.
