Gel Blocking

Gel blocking is a reason of poor performance of many absorbent products available on the market especially when they have high quantity of hydrogel (SAP).

The term gel blocking describes a phenomenon that occurs when a hydrogel particle, film, fiber, etc. is wetted; the surface swells and inhibits liquid transmission to the interior of the product.

Wetting of the interior subsequently takes place via a very slow diffusion process. In practical terms this means that the absorption is much slower than discharge of fluid to be absorbed, and failure of a diaper or sanitary napkin or other absorbent structure may take place well before the hydrogel material in the absorbent structure is fully wet.
