SAP( Super Absorbent Polymer) Superabsorbent polymers are now commonly made from the polymerization of acrylic acid blended with sodium hydroxide in the presence of an initiator to form a poly-acrylic acid sodium salt (sometimes referred to as sodium polyacrylate). This polymer is the most common type of SAP made in the world today. Free absorbency of Distilled water(g/g) :500~600 Free absorbency of saline solution (0.9%NaCl) (g/g):50 min. Centrifugal Retention capacity (CRC) (g/g):33 min. Absorbency under Load (AUL) 0.3 psi:28 min. Absorbency under Load (AUL) 0.7 psi:20 min. Absorption speed (by vorlex Method) s: 70 max. Moisture% :5.0 max. PH: 7.5~8.3 Best Regards
