Polyacrylamide (PAM) CAS#: 9003-05-8
Excellent Flocculation & Thickening Capacity: White granular or powdery linear polymer, including anionic, cationic, nonionic and amphoteric types. It features outstanding flocculation, sedimentation, thickening, drag reduction and adhesion properties, can adsorb suspended particles and form large flocs for fast solid-liquid separation.
Good Compatibility Property: Chemically stable under normal temperature, compatible with inorganic coagulants and many industrial additives; available in different molecular weight and ionic degree grades for diversified wastewater and oilfield scenarios.
Stable Form for Convenient Transport: Uniform granule or powder form, stable under sealed storage, easy to weigh, transport and automatic feeding.
Polyacrylamide (PAM) is a widely used high-efficiency water treatment chemical, low residual monomer, covers a wide range of wastewater treatment, oil exploitation, papermaking and mining application scenarios.
