  • Polyacrylamide (PAM) Prices | News | Database | Trend ...

    Polyacrylamide (PAM) is a water-soluble polymer, physically available as a white crystalline solid. It is a non-ionic compound which forms strong hydrogen bonds with water molecules and hence capable to retain water. This water absorbing and retention quality makes it suitable to be used as a superabsorbent.
