AQUAGEL™ Standard Superporous Hydrogel

AQUAGEL™ superporous hydrogels have the following properties:
• Fast Responsiveness
Conventional hydrogels swell or shrink in response to environmental changes too slowly for many applications. Our AQUAGEL™ superporous hydrogel technology allows preparation of hydrogel systems that change their dimensions in a matter of a minute, regardless of size.
• High Swelling Ratio
AQUAGELs swell not only fast but also to very large sizes. The swelling ratio (swollen size⁄dry size) can be as large as several hundred. To maintain the mechanical strength of fully swollen hydrogels, the swelling ratio can be lowered to less than 100 by increasing the crosslinking density. The enhanced mechanical property can also be obtained by making superporous hydrogel composites and/or elastic superporous hydrogels.
• Elasticity
AQUAGELs swell in water in less than a minute regardless of their sizes. Since more than 90% of the weight of swollen superporous hydrogels is water, they are usually mechanically weak. Akina has developed AQUAGEL™ elastic superporous hydrogels that can stretch more than 100% of their original size. The high elasticity also makes the superporous hydrogels mechanically resilient. The elastic superporous hydrogels are ideal for various applications ranging from oral controlled-release formulations to tissue engineering applications.
