How much is polyacrylamide anionic grade in Germany?

The latest quarter-ending price for Polyacrylamide Anionic Grade in Germany was USD 3425/MT FD Hamburg, underscoring the sustained upward momentum in pricing driven by consistent industrial demand and regulatory pressures. The quarter was devoid of major plant shutdowns or operational disruptions, ensuring a stable supply amid rising demand.

What is anionic polyelectrolyte powder?

Anionic Polyelectrolyte Powder is a medium anionic charged powder polyelectrolyte to be used as a thickener in the direct filtration process to precipitate inorganic suspended solids, waste water. Anionic polyacrylamides are used, among other things, for water clarification and process water recycling.

Can acrylamide be used as an anionic polyelectrolyte?

As the ratio of the acrylic acid to acrylamide goes up in an anionic polyelectrolyte the viscosity built up is considerable which limits the practical use of this method on an industrial scale. Polyelectrolytes are also manufactured by the emulsion polymerisation of acrylamide and a co monomer like acrylic acid or a cationic monomer.

What are anionic polyacrylamides?

Anionic polyacrylamides (PAMs) are a class of synthetic water-soluble polymers (composed of long chains of acrylamide monomer) used as flocculants. They are available in dry powder form, liquid emulsion, and gelatinous blocks.

What is the difference between polyelectrolyte and polyacrylamide?

Polyelectrolyte doses used are very small in relation to the dose of the primary coagulant. Natural polyelectrolyte doses vary between 0.5-2.5 mg/1 whereas polyacrylamide doses vary between 0.05-0.25 mg/1. Polyelectrolytes are added as a coagulant for turbid waters, or after the primary coagulant as a coagulant aid.

Is polyacrylamide a water soluble polymer?

Polyacrylamide (PAM) is a water-soluble polymer, physically available as a white crystalline solid. It is a non-ionic compound which forms strong hydrogen bonds with water molecules and hence capable to retain water. This water absorbing and retention quality makes it suitable to be used as a superabsorbent.
