Absorber is a water retainer that, when incorporated into a soil or a substrate, absorbs and retains large quantities of water and nutrients. Unlike most products that become hydrated, Absorber has the property of easily releasing the absorbed water and nutrients, thereby allowing the plant to have water and nutrients available at will as a function of the absorption – release cycles.
Absorber is a range of super absorbent anionic polyacrylamide polymers. They are cross linked copolymers of acrylamide and potassium acrylate that are water insoluble.
Absorber products have the property of absorbing up to 500 times their weight in distilled water and they become gels.
HOW IT WORKS
The polymer consists of a set of polymeric chains that are parallel to each other and regularly linked to each other by cross-linking agents, thus forming a network. When water comes into contact with one of these chains, it is drawn into the molecule by osmosis. Water rapidly migrates into the interior of the polymer network where it is stored. As the soil dries out, the polymer releases up to 95% of the absorbed water into the soil.
