Polyacrylamide classification: non-ionic (NPAM), cationic (CPAM), anionic (APAM) and diionic (Amphionic PAM).

Application of polyacrylamide:

Polyacrylamide is a general term for acrylamide homopolymer or polymers copolymerized with other monomers. Polyacrylamide (PAM) is one of the most widely used varieties of water-soluble polymers.

Polyacrylamide is widely used in oil extraction, papermaking, water treatment, textiles, medicine, agriculture and other industries. According to statistics, 37% of the total global production of polyacrylamide (PAM) is used for wastewater treatment, 27% for the petroleum industry, and 18% for the paper industry.

Polyacrylamide has good thermal stability and is easily soluble in cold water. The viscosity of its aqueous solution is approximately logarithmic (i.e. linear) with concentration. Polyacrylamide (PAM) with high relative molecular mass and ultra-high relative molecular mass (greater than 2000×10) has very high viscosity, and its aqueous solution has good tolerance to electrolytes.
