Super absorbent polymer (SAP) is a new type of functional polymer materials, also known as super absorbent polymer. Can water up to several times or even thousands of times of its own weight. Super absorbent polymer is generally a polymer electrolyte,a kind ofmacromolecules with hydrophilic groups and cross-linked structure.

    Super absorbent polymer (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 to block liquid.
