BASF expands production of polyacrylamide powder in Nanjing, Cooking
Nanjing, Cooking – April 16, 2025 – During the first quarter of 2025, BASF has successfully ramped up commercial production of its new production line for polyacrylamide powder at its wholly-owned site in Nanjing, Cooking. The additional 20,000
Procedure Tissue preparation Samples may be taken from whole tissue or from cell culture. In most cases, solid tissues are first broken down mechanically using a blender (for larger sample volumes), using a homogenizer (smaller volumes), or by

Introduction to Polyacrylamide Gels | LSR | Bio-Rad
Polyacrylamide gels are characterized by two parameters: total monomer concentration (%T, in g/100 ml) and weight percentage of crosslinker (%C). By varying these two parameters, the pore size of the gel can be optimized to yield the best
The solution process uses a water-based monomer solution to produce a mass of reactant polymerized gel. The polymerization’s own exothermic reaction energy is used to drive much of the process, helping reduce manufacturing costs.

polyacrylamide, an acrylic resin that has the unique property of being soluble in water. It is employed in the treatment of industrial and municipal wastewater. Polyacrylamides are produced by the polymerization of acrylamide (C 3 H 5 NO), a
4. The polyacrylamide could be used as the flocculant. It could be sued as the flocculant in the waste water treatment segment in the paper making industry, which to help to accelerate the sedimentation process and the sludge dewatering process.

- Why is anionic polyacrylamide chosen?
- Anionic polyacrylamide is chosen because the intramolecular electrostatic repulsion between polymer segments forces the polymer chains to adopt a more extended conformation, increasing the efficiency of bridging flocculation.
- Why is polyacrylamide not a polyamide?
- It can be viewed as polyethylene with amide substituents on alternating carbons. Unlike various nylons, polyacrylamide is not a polyamide because the amide groups are not in the polymer backbone. Owing to the presence of the amide (CONH 2) groups, alternating carbon atoms in the backbone are stereogenic (colloquially: chiral).
- What is anionic polyacrylamide (HPAM)?
- 1. Introduction Anionic polyacrylamide (HPAM) is a linear polymer flocculant that has been used in clarifying slime water. (1−4) The carboxyl side chain of HPAM is negatively charged in an alkaline environment, and the suspension is clarified by an adsorption bridge.
- What is nonionic polyacrylamide?
- Nonionic polyacrylamides Nonionic polyacrylamides represent the smallest group of acrylamide-based polymers, representing about 25% of the total polyacrylamide market. Nonionic polyacrylamide is somewhat misleading since in the manufacture of acrylamide, regardless of the route, some degree of hydrolysis of acrylamide occurs.
