English description（英文原文，共 1230 字符）
Product Name:Anionic Polyacrylamide
English Name:Anionic Polyacrylamide
CAS No.:25038-45-3
Aliases:PAM, Polyacrylamide, Flocculant
Molecular Formula:(C3H5NO)n
Physical Properties:White granules or powder, soluble in water, insoluble in organic solvents such as ethanol and acetone. The molecular weight can be classified into low (<1 million), medium (1–4 million), and high (>7 million). The anionic type is mostly hydrolyzed polyacrylamide (HPAM), with a main chain carrying numerous amide groups, high chemical activity, and can be modified into various derivatives.
Uses:Widely used in wastewater treatment, papermaking, mineral processing, oil extraction, metallurgy, building materials, and other industries. As an important oilfield chemical, it serves as a lubricant, suspending agent, clay stabilizer, oil-displacing agent, fluid loss reducer, and thickener, applied in drilling, acidizing, fracturing, water shutoff, cementing, and secondary/tertiary oil recovery.
Technical Specifications:
Purity ≥ 99%
Molecular weight range: low <1 million, medium 1–4 million, high >7 million
Anionicity: 10%–40% (customizable)
Dissolution time: ≤60 min under stirring
Appearance: white or slightly yellow granules/powder
