What is polyacrylamide (PAM)?

Interested in this product? Polyacrylamide (PAM) is a water-soluble polymer made up of acrylamide subunits. It has a unique effect to increase the viscosity of water or promote the flocculation of particles present in water, it can also reduce the frictional resistance between the liquid.

What is polyacrylamide polymer?

Polyacrylamide, also briefly referred as PAM, is commonly a polymer with acrylamide monomers bonded connected by end to end configuration; it is a hard glassy solid at room temperature. Because of the difference in production methods, the products can be white powder, translucent beads and flaky like.

Is polyacrylamide soluble in water?

Figure 1 The synthetic route of polyacrylamide. Polyacrylamide is relatively stable to heat with its solid only being softened at 220~230 °C and its solution subjecting to significant degradation only at above 110 °C. Polyacrylamide is insoluble in benzene, toluene, xylene, gasoline, kerosene, diesel fuel, but soluble in water.

What are the different types of polyacrylamide?

Polyacrylamide comes in various forms such as granular, liquid oil emulsion, tablet, and block forms. Dry polyacrylamide is easier to store, transport, and meter into head ditches and they also have a longer shelf life than liquid forms. However, liquid forms require less agitation to dissolve.

What is the pH range of polyacrylamide?

In the pH range of 3 to 9, it can maintain a good degree of stability; at high pH, the viscosity will be increased gradually. Miscibility: in generally used concentration, polyacrylamide has miscibility with most water-soluble natural or synthetic resins, latex systems, and most of the salts.

What is anionic polyacrylamide?

Anionic polyacrylamide is suitable for higher density, inorganic suspension substance with positive charge and is neutral or basic, with thick suspension particles of 1mm-10mm. Polyacrylamide comes in various forms such as granular, liquid oil emulsion, tablet, and block forms.
