Polymer Gel

Some times Solid Rain is referred as Gel, which is used in Agriculture to save the water.
Polyacrylate is an example of hydrogels or super absorbents. They are called so as they have the ability to absorb and hold a large amount of water. Hydrogels use cross-linked polymers to absorb water. This superabsorbent material is widely used in the manufacturing of diapers for babies. At the present time only three superabsorbent gels are used commercially these are sodium polyacrylate, potassium polyacrylate, and polyacrylamide. The potassium polyacrylate and polyacrylamide are widely used as fire-blocking gels. The superabsorbent gel commonly used to absorb chemical spills is potassium polyacrylate. This superabsorbent is also used to absorb water and store it in the form of gel crystals.
