Potassium Polyacrylate is a kind of super absorbent polymer(SAP), a water-absorbent material with good water-holding capacity. It can absorb water up to several hundred times of its own weight, and turn into the natural gel from within seconds. SAP can be mainly divided into three major categories which are Hygiene grade, Agriculture grade, and Industry grade. The main uses of SAP are absorbing, retaining, or block liquid.
The main chemical composition for agricultural usage is potassium polyacrylate.
