Description

Our sSORB™ Type-A Indicating Yellow Silica Gel is the naturally occurring mineral silicon dioxide that has been purified and processed into a hard, smooth beaded form.  The beads are then saturated with a moisture indicating solution that gives them a yellow/orange color when dry. The beads become a dark green color as they adsorb moisture. It is a narrow pore type silica gel that has a vast network of interconnecting pores with diameters of 20-30A. These pores have a strong affinity for moisture and use physical adsorption and capillary condensation to trap and hold it.

Additional information

Storage

Store sSORB™ Type-A Yellow Indicating silica gel in a dry location to prevent premature water adsorption. Reseal packages after opening to prevent contamination and unintended water adsorption. We recommend that you rotate stock so oldest material is used first. The color changes from yellow (orange) to green as it adsorbs moisture. The color typically begins to changes as the moisture content passes 6% by weight and is complete at 14% by weight. A bright green color indicates moisture saturation and that it is time to replace or regenerate the desiccant.

Typical Applications

This type of silica gel can be used as a primary desiccant or blended with other desiccants in any application where visual control of moisture is required. These applications include: compressed air dryers, gas drying, breathers, for protection of non-consumable packaged goods, drying and storage of flowers and seeds, etc.

Due to the addition of the moisture indicator, sSORB™AY25B Yellow Indicating Silica Gel should not be used in contact with products intended for consumption such as food or pharmaceuticals.
