Super Absorbent Polymer (SAP)


Super absorbent polymer (SAP) is a polymer material with good water absorption and water-holding capacity. It can absorb water up to several hundred times of its own weight, and turn into 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 usStandard strong sea-worthy packing, with inner plastic bag, each bag contains net weight 25kgs, or according to your of SAP are absorbing, retaining or to block liquid. SAP is a highly water absorbent polymer which is a cross-linked poly (sodium acrylate); SAP can absorb 500-1,000 times its weight in water and 50-70 times in synthetic urine; it is essentially water insoluble.
