POLYFON F Kraft lignin is a natural, renewable product derived from wood. POLYFON F is a highly sulfonated, low molecular weight sodium salt kraft lignin.POLYFON F is especially recommended for extruded water dispersible granules..

Kraft lignin is a natural, renewable product derived from wood. POLYFON O is a low molecular weight kraft lignosulfonate with a low degree of sulfonation. Its strong adsorption to substrates provides very stable dispersions. POLYFON O is used as a primary dispersant in dry and water-based agricultural chemicals.

REAX LS is the sodium salt of a chemically modified, medium molecular weight kraft lignin polymer. It is a primary dispersant in disperse dye and agricultural chemical systems where a combination of excellent heat stability, storage stability and low fabric stain are required.

REAX 907 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.
