Overview / Applications

Outline	This product is for research use only. Do not administer it to human. Solubility: Insoluble in water and organic solvent. [ Analytical Chemistry ][ Environmental Analysis ] *Super Absorbent Polymer (Acrylate Type)* Capable of absorbing as much as 400 times its own weight of water! What is a Super Absorbent Polymer? A Super Absorbent Polymer is a polymer characterized by rapid water absorption and swelling when it comes into contact with water, and capable of absorbing as much as several hundred times its own weight. It also has the characteristics of retaining most of the absorbed liquid even if pressure is applied. Therefore, it is used as a disposable diaper or sanitary goods and applied to the fields of agriculture, medicine and civil engineering as water absorbent, moisture absorbent, gelling agent and humectant. Its application as a research reagent is also becoming widespread. This product is a partially neutralized cross-linked poly (acrylic acid) and forms a relatively hard gel by absorbing as much as 400 times its own weight of water.
