Nonionic Polyacrylamide (NPAM)

CAS No.:


Molecular Formula:


Structural Formula:

PAM structure


Water-solubility: Nonionic polyacrylamide is highly water-soluble, which means it can readily dissolve in water to form a clear solution. This property allows for easy handling and application in various processes.

Flocculation and sedimentation: NPAM can act as a flocculant, promoting the aggregation and settling of suspended particles in water. It helps in the clarification and separation of solids from liquids, making it useful in wastewater treatment, mining, and other industries where solid-liquid separation is required.

Rheology modification: Nonionic polyacrylamide can alter the viscosity and flow behavior of aqueous solutions. It can increase the viscosity of water, leading to improved fluid control and enhanced performance in applications like drilling fluids, enhanced oil recovery, and gel electrophoresis.

Stability and compatibility: NPAM exhibits good stability over a wide range of pH values and temperatures, making it suitable for use in diverse environments. It is compatible with other additives and chemicals commonly used in industrial processes, allowing for versatile applications.

Non-toxic and environmentally friendly: Nonionic polyacrylamide is generally considered to be non-toxic and environmentally friendly when used within recommended concentrations. However, as with any chemical substance, proper handling and adherence to safety guidelines are necessary.

Excellent film-forming properties: NPAM can form thin, cohesive films when applied on surfaces. This property finds applications in areas like papermaking, where it helps improve paper strength and retention of fillers and pigments.

It's important to note that the specific properties of nonionic polyacrylamide can vary depending on factors such as its molecular weight, degree of branching, and application-specific formulations.

Nonionic polyacrylamide (NPAM) finds a wide range of applications across various industries due to its versatile properties. Here are some common usages of nonionic polyacrylamide:

Water Treatment: NPAM is extensively used in water and wastewater treatment processes. It acts as a flocculant, aiding in the aggregation and settling of suspended particles, thus facilitating the removal of solids and impurities from water. It helps in the clarification of drinking water, industrial process water, and wastewater treatment plants.

Enhanced oil recovery (EOR):: Nonionic polyacrylamide is employed in the oil and gas industry to enhance oil recovery from reservoirs. It alters the viscosity of the injection water, improving its sweep efficiency and reducing the mobility of the oil. This enables better displacement of the trapped oil and increases overall oil production.

Papermaking: NPAM is used in the paper industry as a retention aid and drainage aid. It improves the retention of fillers, fibers, and fines in the paper pulp, leading to improved paper quality and increased production efficiency. It also enhances the drainage of water from the pulp, resulting in faster drying times and higher paper machine speeds.

Textile and dyeing industry: Nonionic polyacrylamide is employed as a textile auxiliary agent. It can act as a dispersant, helping to evenly distribute dyes and pigments in textile dyeing processes. It also improves the fabric's color fastness, prevents staining, and enhances the uniformity of dye uptake.

Soil conditioning and erosion control: NPAM is used in agriculture and soil management to improve soil structure, reduce erosion, and increase water infiltration. It helps in soil conditioning by improving water retention, reducing soil crusting, and enhancing the stability of soil aggregates. This promotes healthier plant growth and reduces soil erosion caused by water runoff.

Personal care products: Nonionic polyacrylamide is sometimes used in personal care products such as lotions, creams, and hair care products. It can act as a thickening agent, stabilizer, or emulsifier, providing desired texture, viscosity, and stability to the formulations.

Mining industry: NPAM is utilized in mineral processing operations, including flotation and tailings management. It aids in the separation of valuable minerals from ores by acting as a flocculant or dispersant. It can improve the efficiency of solid-liquid separation processes and reduce water consumption.

Gel electrophoresis: Nonionic polyacrylamide gels are commonly used in molecular biology techniques like gel electrophoresis. These gels provide a medium for the separation and analysis of DNA, RNA, and proteins based on their molecular weight and charge.

It's worth noting that the specific applications and formulations of nonionic polyacrylamide can vary depending on the desired results and industry requirements.
