Blue Indicating Silica Gel Beaded 4X8 Mesh
- Commercial Bead Sizes (inches) : 2-5mm
Blue Indicating Silica Gel Beaded 4×8 Mesh 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 deep blue 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). The color changes from blue to purple to pink as it adsorbs moisture.
