Products Description of Sodium polyacrylate CAS#9003-04-7
Sodium polyacrylate is a white powder. Odorless and tasteless. It is highly hygroscopic. It is a high molecular compound with hydrophilic and hydrophobic groups. It slowly dissolves in water to form a very viscous transparent liquid. The viscosity of its 0.5% solution is about Pa•s. The viscosity is not caused by water swelling (such as CMC, sodium alginate), but because the ionic phenomenon of many anionic groups in the molecule causes the molecular chain to grow, the apparent viscosity increases, and a high viscosity solution is formed. Its viscosity is about 15-20 times that of CMC and sodium alginate. Heating treatment, neutral salts, and organic acids have little effect on its viscosity, but the viscosity increases in alkaline conditions. It is insoluble in organic solvents such as ethanol. It does not decompose when heated to 300 degrees. The viscosity changes very little after long-term storage and is not easy to corrupt. Because it is an electrolyte, it is easily affected by acids and metal ions, and the viscosity decreases. When it encounters divalent or higher metal ions, it will not decompose.
