Calcium Lignosulfonate

Calcium lignosulfonate (40-65) is an amorphous light-yellow-brown powder obtained from the sulfite pulping of softwood. The organic framework of the additive is a sulfonated random polymer of three aromatic alcohols: coniferyl alcohol, p-coumaryl alcohol, and sinapyl alcohol, of which coniferyl alcohol is the principle unit.

Application

 lignosulfonates can be used as binders, dispersants, liquefiers or surfactants in many different industries. Contact your LignoStar sales representative for sample material and more information about the possibilities with StarLig products in your sector or explore the functional fields below:

Starlig Binders

The binding power of StarLig products forms the basis for sustainable alternatives, in several fields of business. Just a small addition of specific types of StarLig can already bring substantial efficiency gains.

Typical fields of application include: adhesives, agriculture, carbon black, ceramics, fertilizers, foundry processes, infrastructure, particle board and compound feed.

Starlig Dispersants

The dispersant characteristics of StarLig products can be applied in many different fields as well. For this purpose, the application of StarLig lignosulfonates leads to substantial cost savings in the field of dyes and pigments, oil and asphalt emulsions, fertilizers, mining and minerals processing, oil exploration and water treatment.

Starlig Liquefiers

For construction chemicals and battery expanders, StarLig products are widely used as liquefiers and plastifiers. StarLig increases the fluidity of the mass, reducing the amount of water required.

Starlig Surfactants

Typical applications for StarLig surfactants can be found in the field of industrial detergents, leather tanning, microelements and crop protection.
