Product Details

Polyacrylamide is a type of water-soluble high-molecular polymer formed by the polymerization of acrylamide monomers or copolymerization with other monomers. Its molecular structure contains a large number of amide groups, and through modification, carboxyl groups, quaternary ammonium groups and other groups can be introduced to form products of different charge types.

Product Usage

Polyacrylamide (PAM) is an important water-soluble polymer widely used in water treatment, oil recovery, papermaking, and mining industries. In water treatment, it acts as a flocculant and coagulant aid to effectively remove suspended particles and improve water clarity. In the oil industry, it is used in enhanced oil recovery (EOR) to increase crude oil extraction efficiency. In papermaking, it serves as a retention and drainage aid to improve paper quality and production efficiency. It is also applied in mineral processing for solid-liquid separation, offering excellent flocculation performance and chemical stability.
