Polyacrylamide is an organic flocculant polymer, which is insoluble in nonpolar solvents, and has good flocculation. This can reduce friction resistance between liquids and can be divided into anions, cations, non-ionic and amphoteric types. Polyacrylamide is white powder or fine granule. Softening temperature is 210 degrees.
