So Sponge innovation: custom and patented materials to regulate humidity

A mesoporous material to capture humidity from the air

So Sponge products consist of a chemically neutral mineral material, organized on several size scales:

Nanocrystals
Micrometric powder, formed by aggregation of nanocrystals.
A millimetric deposit, formed from the powder.

The space between the nanocrystals constitutes the active porosity for the adsorption of water vapor.

Flexible properties

Pore size defines at what humidity level the material starts to adsorb.

The So Sponge material starts to work when the humidity level exceeds 60%, which is slightly above the recommended level for ambient air.

By modulating the size of the pores, one can choose to favor intermediate humidity levels (between 60 and 80%) or very high humidity levels (> 80%).

An original layout for more efficiency

Air Sponge is the only humidity regulator in the form of a flexible tape. Resulting from more than a year of development, it is a versatile product, which can be adapted for each application:

grammage: up to 220 g/m2
mono/double sided
with/without pre-adhesive for quick fixing

Because of its very thin thickness, the So Sponge tape captures water vapor very quickly and therefore remains effective even in the most extreme conditions.
