High Quality Polyacrylamides - Camachem
Nonionic polyacrylamide is suitable for separation of suspended solids in organic and inorganic mixtures, and the solution is acidic or neutral. Nonionic polyacrylamide can be used in textile sizing to improve the viscosity, permeability and desizing performance, make fabric with antistatic properties, and reduce sizing rate and machine damage.

Is non ionic polyacrylamide a water soluble polymer?
Non-ionic polyacrylamide is a water-soluble high molecular polymer or polyelectrolyte. The characteristics of nonionic polyacrylamide PAM can be simply divided into the following three points: It has relatively good water solubility and can be completely dissolved even in cold water.
What are the different types of polyacrylamide?
There is a wide range of diverse solution polyacrylamides available in the commercial marketplace (anionic, cationic, and nonionic). They cover a wide range of charges and can range in molecular weights from the thousands to one or two million Daltons.
What is a high-molecular-weight nonionic polyacrylamide?
High-molecular-weight nonionic polyacrylamides are routinely used in the mineral processing industries as thickeners and flocculants [36–38]. The product types for polyacrylamides are solutions, liquids (emulsion or dispersion), and dry powders. The forms each have their own set of advantages and disadvantages as will be discussed in the following.
What is cationic polyacrylamide?
Cationic polyacrylamides make up the second-largest portion of the polyacrylamide market, only slightly behind anionic polyacrylamides, and is by far the largest group of cationic polymers used on the industrial scale. Very high molecular weights can be achieved and are usually on the order of 5–15 million g/mol when used in wastewater treatment.
Can nonionic polyacrylamide be used as a sewage treatment agent?
Nonionic polyacrylamide can be used as a sewage treatment agent for acidic slurry, making the suspended particles flocculate and precipitate. * You have to Login or Register to download this file.
