Moisture Adsorbing Board (MAB)


Custom Moisture Adsorbing Board for Limited Space Applications

The formation of condensation in the air is one of the significant causes of damage to products, system failures, and a dramatic reduction in reliability and performance of the environmentally vulnerable medical equipment, electronic circuits, and devices.

When space is limited, the moisture adsorbing board offers an ideal alternative to regular desiccant absorbent sachets or bags—manufactured in sheet form, which enables easy cutting in different required sizes.

MAB also prevents the loss of desiccant dust and contamination, resulting from the broken or damaged desiccant sachets or bags. The moisture absorber maintains a clean and dry external environment.

The MAB is available in sheet form and can be customized in varying thicknesses depending on its application. The standard size is 295mm x 205mm x 1.6mm or A4 sheet size dimensions.
