Cationic polyacrylamide (CPAM) is a linear polymer compound that can form hydrogen bonds by affinity and adsorption with many substances. Cationic polyacrylamide according to national standard specification, the ion degree content should be 20-80%, can be called qualified cationic polyacrylamide.

Properties: polyacrylamide, alias PAM, is a glassy solid. It is easy to absorb water, and the absorption rate is different with the characteristics of derivative ions. Polyacrylamide soluble in water, also soluble in acetic acid, ethylene glycol, glycerol and amine and other organic solvents, insoluble in ketone, ester, hydrocarbon and other organic solvents. Cationic PAM shows positive electroactivity in both acidic and alkaline media, which can be used to flocculate and phagocytic wastewater with suspended particles and negative charge. Long-term thermal decomposition, decomposition temperature in 200℃ above. In the absence of oxygen, 210℃ carbonization into black powder.As required, polyacrylamide can be processed from non-ionic type into anions, cations and mixed ions of Yin and Yang to form four types of products.
