With limited space, the moisture adsorbing board (MAB) is an alternative to traditional desiccant sachets. The desiccant sheet can be cut, punched, or thermoformed into specific shapes or sizes, offering flexibility in packaging. Its uniform thickness makes it easy to pack.
Alternative to Traditional Desiccant Sachets
The desiccant is not water-soluble, corrosive, or deliquescent and can be securely fixed using mechanical retention. It produces no dust. The moisture absorber provides moderate to long-term hygroscopicity and has a printable sheet surface for customisation.
The desiccant sheet comes in a standard sheet size of 295mm x 205mm x 1.6mm (the dimensions of an A4 sheet) and can be customised to meet specific requirements. This sheet form desiccant is ideal for protecting against moisture and is dust free.
The typical adsorption value of the MAB is 0.006 grams per cm2, which enables the calculation of the required quantity. The manufacturing process involves using polyethene plastic with active silica gel to create the MAB, and it can operate within a standard temperature range of -40ºC to 70ºC.
