Water Absorbent Polymer, also known as Super Absorbent Polymers, can be referred to as polyacrylate polymers that have the capacity to absorb higher amount of water. The ability of the Water Absorbent Polymer to absorb moisture depends on the ionic concentration of the aqueous solution. Water Absorbent Polymers find its use in various applications.
The total absorbing and swelling capacity of the polymer gets controlled by the type and degree of cross-linkers that are used to make the gel. Low-density cross-linked Water Absorbent Polymer generally shows a higher absorbent capacity and swell to a larger degree. Water-absorbing polymers, which are considered as hydrogels when cross-linked, absorb aqueous solutions with the aid of hydrogen bonding with water molecules.
