Description

 

Sodium Polyacrylate is a superabsorbent polymer, having the good absorbance, retention of water properties.Sodium polyacrylate is an anionic polyelectrolyte with negatively charged carboxylic groups in the main chain, with the formula (C3H3NaO2)n. Sodium Polyacrylate uses finds in various consumer products like sequestering agent, or chelating agent in detergents,thickening agent in diapers, pets pad, water retaining material, instant snow.As a thickening agent, sodium polyacrylate can increase the viscosity of water-based compounds, which increases their stability.In diapers, sodium polyacrylate polymer will absorb the water molecules found in urine, increasing the amount of liquid the diaper can hold while at the same time reducing the risk of diaper rash by promoting a dry environment. Florists commonly use sodium polyacrylate to help keep flowers fresh. Sodium polyacrylate has been included in the coatings of sensitive electrical wiring to keep moisture away from the wires.
