Yellow Silica Gel

sSORB yellow indicating silica gel is a synthetically modified silicon dioxide that has been purified and processed into a hard, smooth bead. The beads are then saturated with a moisture indicating solution that gives them a yellow (orange) color when dry. It is also known as a narrow pore silica gel and has a vast network of interconnecting pores with diameters of 20-30Å. These pores have a strong affinity for moisture and use physical adsorption and capillary condensation to trap and hold it. Silica gel will remove moisture at temperatures as high as 220˚F, but is best used at room temperature (70-90 ˚F) and high relative humidity (60-90%Rh).

Description

The color typically begins to change as the moisture content passes 6% by weight and is complete at 14% by weight. The bright green or clear color indicates moisture saturation and that it is time to replace or regenerate the desiccant.

Typical Applications of Yellow Silica Gel:

As primary desiccant or blended with other desiccants in any application where visual control of moisture is required, such as compressed air dryers, gas drying, breathers, for protection of non-consumable packed goods, drying, and storage of flowers and seeds, etc. Due to the addition of the moisture indicator, sSORB yellow indicating silica gel should not be used in contact with products intended for consumption such as food or pharmaceuticals.

Handling & Storage

Store sSORB silica gel in a dry location to prevent premature water adsorption. Do not store super sacks outside; ultraviolet radiation and other adverse conditions will negatively impact its integrity and may eventually cause the bag to fail. Reseal packages after opening to prevent contamination and unintended water adsorption. We recommend that you rotate stock so the oldest material is used first.
