1. Product Identification
1)Produt name: ProSodium polyacrylate
2) CAS No.: ********7
3)Molecular Structure:
4) Formula: (C3H3NaO2)n
5) Density: 1.*2 g/mL at *5℃
2. Product properties
It is a kind of high molecular polymer with hydrophilic group. It appears odorless and tasteless white powder or granule. It will form transparent solution of great viscosity while slowly dissolved into water. The viscosity is engendered by the dissociation of numerous anions and hence causes the growth of molecular chain not by expansion of water absorption that normally happens to CMC and sodium alginate. The viscidity is about *5~*0 times higher than CMC and sodium alginate. It shows high alkali-resistant, minor change in viscosity after longtime storage, and not easily decaying.

4. Handling Precautions:
1)Method of dissolve
Add Sodium polyacrylate slowly to rotating water, then keep it dissolving for *0 minutes.
2) Different water quality influence on viscosity of Sodium Polyacrylate
There is a great difference in viscosity between hard water and soft water. It would be better to dissolve it in pure water.
3) Salinity influence on viscosity of Sodium Polyacrylate
The viscosity of Sodium polyacrylate declines with the increase of salinity
4) pH influence on viscosity of Sodium Polyacrylate
The viscosity of Sodium polyacrylate is relatively stable between pH 8 to *0, but declines in acid environment.
