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.
