Polyacrylamide (PAM, CAS 9003-05-8) is sold by dozens of suppliers in a bewildering range of grades. Buyers who focus only on price often end up with the wrong ionic type or an inconsistent product that performs differently from batch to batch. This purchasing guide covers the specification sheet, the COA, packaging, storage and the supplier

Most people meet polyacrylamide (PAM, CAS 9003-05-8) as a water treatment chemical, but agriculture is one of its oldest and most valuable uses. Applied to soil or irrigation water, PAM binds soil particles, cuts erosion, improves infiltration and clarifies irrigation runoff. This guide explains how agricultural PAM works and how to apply it correctly. 1.

Polyacrylamide (PAM, CAS 9003-05-8) is not one product — it is a family. Anionic, cationic and nonionic grades differ in charge, molecular weight and application, and picking the wrong grade wastes chemical and money. This guide explains the difference between the three ionic types and how to choose the right grade for your water, slurry

Papermaking is one of the most chemically demanding processes in industry. The wet end carries fibers, fines, fillers and dissolved anionic “trash” that must be retained, drained and controlled — and cationic polyamine (CAS 42751-79-1) is a versatile tool for all three jobs. This article explains how polyamine is used in the paper mill, where

Oil-water separation is one of the hardest jobs in water treatment. Produced water from oilfields carries emulsified oil, high salinity and temperature, and fine solids — conditions that defeat many conventional coagulants. Cationic polyamine (CAS 42751-79-1) has become a workhorse chemical for this duty because of its high charge density and salt tolerance. This article
