The Science of Super Absorbent Polymers

The Science of Super Absorbent Polymers

Go ahead and call us geeks, but the team here at Healthwick loves playing with Super Absorbent Polymers! 

SAP is perhaps the most important material in an absorbent incontinence product. These tiny but complex hydrogel beads that can absorb up to 500 times their weight in liquid and swell up to 60 times their size. 

A teaspoon of SAP can theoretically absorb up to 2.5 liters of water! Check out our little animated image of us testing a full 250mL of liquid to one half teaspoon of SAP.

Aside from the wild absorbent properties, SAP also helps to reduce urine odour by trapping liquid in a solid suspension. And, of course, they wick away urine, which helps to promote good skin health.

SAP is, however, extremely expensive to manufacture. Premium products which contain a high level of SAP are typically 2 to 3 times more expensive than traditional retail incontinence products.
