SAP are crosslinked networks of flexible polymer chains. The polymer chains are shrunk befor absorbing water. When water comes into contact polymer chains, these chains are expanded. Water is trapped tightly within networks.

Super absorbent polymer

Superabsorbent Polymer (SAP) is a material capable of absorbing several hundred to 1,000 times its own weight in water. Even when subject to pressure, this polymer securely retains the absorbed liquids. In 1978, we were the first in the world to begin commercial production of SAP. Today, SAP is used in a wide range of applications, from hygiene materials used mainly in disposable diapers and sanitary products to non-hygienic applications such as agriculture & horticulture, pet, construction and civil engineering, etc.
