Cationic Polyacrylamide

Cationic Polyacrylamide


Cationic Polyacrylamide is a water-soluble high molecular polymer. Since its molecular chain contains several absorption and polar groups, it can build a bridge between particles by absorbing the suspected solid particles in water and condense particles into big flocs by neutralizing electrical charge.

Therefore, Cationic Polyacrylamide has the effect of accelerating solid-liquid separation, promoting filtration, etc. It is mainly used in flocculation and sedimentation of various industrial and domestic sewage, sedimentation and air flotation, sludge concentration and sludge dehydration.

Besides, we also produce modified Cationic Polyacrylamide as the building putty additive which has excellent performance with salt and degradation resistance properties.



Type Cationic
Appearance White powder
Solid content ≥90%
Molecular weight 400-1000(104)
Ion Density 5-80%


This series Cationic Polyacrylamide has strong effect in flocculation, and it has functions in purification, clarification, sedimentation promotion, filtration promotion, thickening, and other aspects which make it can fulfill the requirement of several industries like wastewater treatment, liquid waste disposal, sludge thickening and dehydration, mineral separation, coal washing, and papermaking.



1. Good solubility and can be easily dissolved even in cold water.
2. Add little can already achieve great flocculation effect. Generally, adding 0.01-10ppm (0.01~10g/m3) will bring a full effect.
3. Use our Cationic Polyacrylamide together with inorganic flocculants (poly-ferric sulfate, poly-aluminum chloride, poly-ferric chloride salts etc.) can achieve better effect.
