Silica gel beads or crystals are composed of 97% silicon dixoide and 3% alumina with widely distributed porous channels to allow maximum internal surgace area for water molecule absorption. Silica gel helps in reaching dew points of -40 °F and lower than this in air or gas drying applications thereby lowering humidity to around 40% until it is saturated.
Silica gel blue is a selective adsorbent containing cobalt chloride which is responsible for color changes in gel beads from blue to pink when it free from moisture and it is eventually moisture intake indicating gel the need ti replenish the gel. Its adsorption capacity varies from 34-38 at the rate of 100% humidity depending on the crystal particle size which comes in the form of 1-3 mesh, 3-4 mesh, 3-8 mesh or 5-8 mesh and beads size ranging from 2-5mm, 3-5mm and 5-8mm.
