Silica Gel Non-Indicative Type (White)
The color of this type of Silica Gel is white. The main property of this Silica is that it does not give any indication of use. The colour remains unchanged and therefore, it is not easy to ascertain by just visualizing whether the absorption capacity of the Silica Gel is fully utilized.
Silica Gel Indicative Type (Orange)
It is produced by impregnating white Silica Gel with Phenolphtaleine due to which the colour of Silica Gel turns orange. Orange indicating Silica Gel is gradually replacing blue Silica Gel as the blue mixture is presumed to cause cancer. This orange Silica in turn changes to a translucent green after it absorbs moisture. The colour change occurs at 5 - 9 RH, so it does not indicate saturation of the Silica Gel, rather there is a lot of adsorption capacity remaining after the colour change has taken place. Orange Silica is widely used in aviation, defence, construction and power industries.
