Polyacrylamide (PAM) is a high molecular weight, linear polymer widely recognized for its powerful flocculation properties. As an effective water treatment chemical, PAM works by neutralizing suspended particles through electrical interaction and bridge adsorption, promoting the aggregation of solids for easy separation.
One of PAM’s standout features is its ability to dramatically reduce fluid friction, cutting it down by 50–80% with just a trace amount added to water. It also serves as a thickening agent, especially under neutral and acidic conditions. At pH levels above 10, PAM undergoes hydrolysis, forming semi-network structures that further enhance its thickening effect.
Based on its ionic character, Polyacrylamide is categorized into non-ionic, anionic, and cationic types. Its amide groups allow the formation of hydrogen bonds, giving it excellent water solubility and high chemical reactivity. This makes PAM easily modifiable into branched or cross-linked variants through grafting techniques.
Thanks to its adaptability and efficiency, PAM is extensively used across industries such as:
