Cationic polyacrylamide (CPAM) appearance is white powder. It is a linear polymer compound. The molecular weight ranges from 8 million to 12 million. Ionicity from 20% to 55% has good water solubility and can be dissolved in water at any ratio and insoluble in organic solvents. suitable for the treatment of wastewater with negative charge and rich in organic matter.

Features
1. Good water solubility, can be completely dissolved in cold water.
2. Adding a small amount of cationic polyacrylamide products can get a great flocculation effect. Generally only need to add 0.01~10ppm (0.01~10g/m3) to fully play its role.
3. Using cationic polyacrylamide products and inorganic flocculants (polyferric sulfate, polyaluminum chloride, iron salt, etc.) at the same time can show greater effects.
