Silica Gel Bags

The use of silica gel desiccant bags provides an economic way of protecting against moisture damage during transit and storage. These bags are filled with non-indicating beaded silica gel desiccant with capacities ranging from 1g to 500g.

Silica gel desiccant is synthetically produced from sodium silicate and has an adsorption capacity of approximately 25% (by weight) at a relative humidity of 50% at 25°C.

Silica gel bags are ideal for general packaging applications, electrical/electronic enclosures and communications equipment.

The addition of a colour 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.

Brownell can also supply silica gel bags that conform to Defence Standard 81-86 and U.S. Military Standard MIL-D-3464.
