Lignosulfonates

Lignosulfonates are byproducts of the sulfite wood-pulping process, captured and refined into a family of natural polymer dispersants. The lignin backbone — substituted with sulfonate groups — gives the molecules their characteristic ability to disperse and deflocculate clay particles, which is exactly what’s needed in clay-based drilling fluids that have thickened from contamination. Five Rivers Materials supplies all three primary grades — sodium, calcium, and ferrochrome (FCLS) — for the full range of mud-system conditions.

Beyond oilfield, lignosulfonates are heavily used in industrial applications: as water-reducing admixtures in concrete (one of the most cost-effective plasticizers available), as pellet binders in animal feed manufacturing, as dust suppressants on roads, and as dispersants in ceramic and tile production. The product is renewable, biodegradable, and economically priced relative to synthetic alternatives.
