Polyacrylamide with CAS number 9003-05-8, formula (C3H5NO)n, is simply called PAM, a widely used flocculant in water purifier, water treatment, wastewater treatment, mining, paper-making, etc..
There are three types polyacrylamide, Anionic Polyacrylamide, Cationic Polyacrylamide and Non-ionic polyacrylamide.
Anionic polyacrylamide is high molecular weight polymer with different anionic charge,used for industrial and potable water treatment, paper mills and mining industry.

PAM Functional principle
Flocculation Mechanism: Adsorbing suspension particles, polymer chains entangle and cross-link each other to form bridging, and make flocculation structure enlarge and thicken, and has the functions of surface adsorption and electric neutralization. Reinforcing Mechanism: PAM molecule chain and dispersed phase form bridging bond, ion bond and covalent bond to increase combination strength.
Packing:
25kg/plastic enhanced paper bags with inner plastic bag, 25kg/PE bags
Storage and shelf life:
PAM polyaceylamide polymer should be storaged in a dry and cool warehouse with 24 months validity.
Solution make up:
Solution should be made up at 0.1-0.3% solid. Make-up water temerature should be between 10 oC to 40 oC for optimum product performance. Following dispersion into agitated water, stirring should be continue for about an hour. The liquid polyacrylamide are stable for one week.
