Molecular sieve desiccants

Molecular sieve desiccant bags provide the perfect solution to packaging and equipment applications that require low relative humidity levels. Standard bag capacities range from 3g to 500g.

Molecular sieves desiccant is synthetically produced from alumina silicates and has an absorption capacity of approximately 20% (by weight) at a relative humidity of 50% at 25°C.

The main advantages of using molecular sieves desiccant are:

High absorption efficiency at high temperatures

Ability to maintain a low relative humidity

Rapid adsorption performance

Typical applications include, general packaging, electrical/electronic enclosures, electro-optical and optical equipment.

The addition of a color change indicator card will provide a visual indication of the relative humidity level within the packaging or enclosure. This provides an important check to ensure that the desiccant is still active.

We can also supply molecular sieve bags conforming to Explosives Compatibility Specification HR904.


Desiccant Type: Beaded Molecular Sieves

Nominal absorption capacity (by weight): 20% at 50% RH and 25°C

Operating temperature range: -40°C to +70°C
