REAX 88B is the sodium salt of a low molecular weight, highly sulfonated kraft lignin polymer. It is used in specialized applications where specific properties such as high metal complexing capacity, acid solubility, or superior viscosity reduction are required.

REAX 280 is a high quality, dry powder sodium lignosulfonate product. It is manufactured in a sodium sulfite mill producing dissolving cellulose from a softwood feedstock. The raw material from the dissolving pulp process is fermented to greatly reduce the free sugars. Typical applications include: dispersants in textile dyestuffs and agrochemicals along with other industrial formulations.

REAX 81A is the sodium salt of sulfonated modified kraft lignin. It is used in a broad range of dye applications where grinding efficiency and good heat stability are required. It is also used in dry and water-based agricultural formulations.

REAX 85A is the sodium salt of a chemically modified medium molecular weight kraft lignin polymer. It is a primary dispersant in disperse dye formulations where heat and storage stability are required.
