Cationic Polyacrylamide CPAM is a linear polymer compound. Because it has a variety of active groups, it can adsorb hydrogen bonds with many substances and has the functions of removing turbidity, decoloring, adsorption, adhesion and so on.

Anionic Polyacrylamide APAM is white powder. Its water solubility is good, can dissolve in any proportion of water and insoluble in organic solvents.

Non-ionic polyacrylamide is a water-soluble polymer or polyelectrolyte. Because its molecular chain contains a certain number of polar groups, it can accelerate the settlement of particles in the suspension. It has a very obvious effect of speeding up solution clarification and promoting filtration. It is highly water-soluble and can be completely dissolved in cold water. Adding a small amount of non - ionic polyacrylamide can obtain a great flocculation effect.

The product chain of amphoteric polyacrylamide has not only the negative charge of carboxyl group after hydrolysis of acrylamide, but also the positive charge of vinyl group. Therefore, a amphoteric irregular polymer with both positive and negative charges on the molecular chains is formed.
