SAP Super Absorbent Polymer are prepared from acrylic acid and a cross-linker by solution or suspension polymerization. The type and quantity of cross-linker control both the swelling capacity and gel modulus.

 

Super Absorbent Polymer is a new type macro molecular synthetic material that can absorb water of hundreds times of its weight in a short time. It is one kind of functionality macromolecule polymer which is non-toxic, non-irritating and non-corrosive. It can not conflagrate and blast.

 

Super Absorbent Polymers, otherwise known as SAP, absorbent polymers, absorbent gels, super soakers, super slurpers, gel crystals, are materials that swell in water to form a clear gel made up of separate, individual particles. Unlike a sponge, in which water can be wrung out easily, the hydrated gel particles retain the absorbed water even under pressure. This unique ability to hold absorbed water, even against pressure, is the primary benefit of using super absorbent polymers.
