Moisture Adsorbing Board (MAB)

Description

The Moisture Adsorbing Board (MAB) is an alternative to the typical desiccant sachets where space is limited. Available in a sheet form, the MAB can be cut into any size to fit into confined spaces, preventing any contamination from desiccant dust. The MAB is available in a standard sheet size of 295mm x 205mm x 1.6mm or in the dimensions of an A4 sh. The size and shape of the MAB can also be customised to meet different specific requirements. It has an average adsorption value of 0.006 grams per cm2 to calculate the quantity of Moisture Adsorbing Board needed. Manufactured from polyethene plastic with active silica gel, it has an operating temperature ranging from -40ºC to 70ºC.
