Sodium polyacrylate is a white powder. Odorless and tasteless. Very hygroscopic. Polymer compounds with hydrophilic and hydrophobic groups. Slowly dissolves in water to form a very viscous transparent liquid. The viscosity of its 0.5% solution is about Paâ?¢s. The viscosity is not caused by water absorption and swelling (such as CMC, sodium alginate), but due to the many anionic groups in the molecule. The ionic phenomenon causes the molecular chain to grow and the viscosity increases to form a highly viscous solution. Its viscosity is about 15-20 times that of CMC and sodium alginate. Heat treatment, neutral salts, and organic acids have little effect on its viscosity, but when it is alkaline, the viscosity increases. Insoluble in organic solvents such as ethanol. Strong heat to 300 degrees does not decompose. The long-term viscosity changes very little, and it is not easy to decay. Because it is an electrolyte, it is susceptible to the influence of acid and metal ions, and the viscosity is reduced.
