series form molecular weight product example; flopam: powder: high: fam 4802 /fam 8401: flostrength: liquid: very low: rsl 8391
The amphoteric polyacrylamide (PAM) produced by our Company under the trade name of LHPAM, is made from acrylic cationic monomer, acrylamide monomer and a hydrolyzing agent through a copolymerization process.Through infra-red sqectrum analysis, it is shown that the molecular chain of the product has not only carboxyl anionic charges resultion from the hydrolysis of acrylamide, but also
Molecular Weight of Amphoteric Polyacrylamide: How it
Amphoteric polyacrylamide (AmPAM) is a linear water-soluble polymer that has been applied in papermaking as an agent for flocculation, retention, filtration, and dry-strength improvement. However, AmPAM with different ranges of molecular weight (MW) have different properties in these processes.

1. Industrial water treatment Amphoteric polyacrylamide has been widely used for industrial water treatment, oil refinery plants and mining etc. Amphoteric polyacrylamide has a better performance and efficiency than the mono-ionic polyacrylamide, especially when the water condition is complicated, or the water condition is keep changing, because its ability to decrease the surface tension of
Synthesis and characterization of amphoteric polyacrylamide by dispersion polymerization in aqueous salts solution Amphoteric terpolymers composed of acrylamide, 2-methylacryloylxyethyl trimethyl ammonium chloride, and 2-acry- method is that it could obtain both high molecular weight and high reaction rate. However, there are some
High Molecular Weight Polyacrylamide Pam Amphoteric
High molecular weight Polyacrylamide PAM amphoteric polyacrylamide Product Description PAM is a water-soluble polymer, the appearance of a white or yellowish powder, easy to absorb water, long-term thermal decomposition, the decomposition temperature above 200 ℃, under anaerobic conditions, 210 ℃ carbonized black powder.
Amphoteric polyacrylamide (AmPAM) was prepared successfully through seeded dispersion polymerization with acrylamide, methacrylatoethyl trimethyl ammonium chloride and acrylic acid as comonomers in ammonium sulfate solution. It was characterized by 1 H nuclear magnetic resonance (1 H NMR) and elemental analysis. The particle morphology and
Polyacrylamide – PAM
Polyacrylamide(PAM), often referred to as “polymer” or “flocculant”. It is a long chain, linear organic polymer made up of individual monomer units with the molecular formula of C3H5NO and molecular weights ranging from 3,000,000 to 30,000,000 Daltons. PAM is a dry white or light yellow powder similar in shape to table salt.

Design and Study of a Novel Thermal-Resistant and Shear
The amphoteric polyacrylamide was characterized by Fourier transform infrared (FTIR) spectroscopy, nuclear magnetic resonance spectroscopy (1H NMR), elemental analysis, thermogravimetric analysis (TG), and scanning electron microscopy (SEM). The amphoteric polyacrylamide exhibited excellent salinity tolerance.

- What is cationic polyacrylamide flocculant?
- Cationic polyacrylamide is widely used for municipal sewage treatment. Its sludge dewatering qualities make it the best for sewage treatment. Cationic polyacrylamide flocculant is grouped depending on its levels of ionicity. The ionicity levels include strong, medium, and weak.
- What are the different types of polyacrylamide flocculants?
- 1. Introduction It is well known that polyacrylamide (PAM), which is a type of water-soluble polymer, is widely used in industrial wastewater treatment as a flocculant , . In general, these flocculants can be divided into three groups, depending on the nature of their charge, i.e., cationic-PAM, anionic-PAM and non-ionic-PAM.
- Is grafted flocculant effective compared to commercial cationic polyacrylamide?
- The grafted flocculant was found to be effective compared to commercial cationic polyacrylamide.
- What are the applications of polyacrylamide (PAM)?
- It is widely used in many fileds like Water Treatment, Oil Exploration, Sludge Dewatering, Paper Making, Textile, Sugar Making, Coal washing and Incense Making, etc. Keywords: PAM, Polyacrylamide, Anionic PAM, Cationic PAM, Nonionic PAM, Flocculant, Acrylamide resin, Acrylamide gel solution, Coagulant, APAM, CPAM, NPAM.
