Super Absorbent Polymers are a type of polymer that can absorb and retain large amounts of water or other liquids, sometimes up to hundreds of times their weight. They are used in a variety of products such as disposable diapers, sanitary napkins and agriculture as soil conditioners.
SAPs are created by cross linking polymers, which creates a network of polymer chains that can trap water molecules within their structure. The cross linking also makes the polymer insoluble, allowing it to retain the absorbed water without dissolving or disintegrating.
One of the benefits of using SAPs is that they can greatly reduce the amount of waste generated by products like diapers, as they allow for a much longer use before needing to be changed. Additionally, SAPs are used in agriculture to improve water retention in soil, allowing for more efficient use of irrigation and potentially reducing water usage.
