Polyacrylamide CAS No.: 9003-05-8 PAM

Polyacrylamide (PAM) is a high-molecular-weight, water-soluble polymer produced by free-radical polymerization of acrylamide monomers. Its molecular chains are rich in amide groups that can be ionized or chemically modified to yield anionic, cationic, or non-ionic variants, delivering outstanding flocculation, thickening, drag-reduction, and surface-adsorption capabilities. PAM is widely used in water treatment, oil & gas extraction, papermaking, mining, agriculture, and more.

Description

Product Description：

Polyacrylamide (PAM) is a versatile, high-molecular-weight water-soluble polymer formed by free-radical polymerization of acrylamide. Its anionic, cationic, or non-ionic variants provide rapid flocculation, thickening, and drag-reduction. PAM is the go-to additive for water treatment, oil & gas, paper, mining, and agriculture.

Types & Models:

Technical Specifications:

Performance：

  1. Flocculation: Rapid settling of suspended solids via charge neutralization and bridging.
  2. Thickening: 0.1 % solution viscosity 3 000–5 000 mPa·s (non-ionic).
  3. Drag reduction: Up to 80 % friction reduction in oil-field fracturing.
  4. Eco-profile: Non-toxic polymer; trace monomer acrylamide is toxic—residuals must be controlled.

 

Application Fields:

Packaging & Storage:

Packaging: 25 kg/bag; customizable big bags or 1 kg packs.

Storage: Keep in a cool, dry place; 24-month shelf life (protect from moisture & sun).
