Diapers should be capable of absorbing liquid. Layers of cellulose fibers did the job in the days before the advent of superabsorbent polymers. But that old method had a major disadvantage: once under pressure, the fluid that was held inside was able to seep through to the diaper's surface. That's why absorbent polymers were invented.
They are crosslinked polymers that form a gel when they absorb fluid. They provide a major benefit: they trap liquids and won't release them, even under extreme pressure.
Most of the superabsorbent polymers produced worldwide are used to manufacture modern baby diapers – and as one of the leading global supplier of these remarkable polymers, we are the undisputed experts in the field.
