Silica gel white, beaded or granular foam, that comes in many meshes and mm size for use in many industrial solutions of the needed selectively absorbency.
The activated white silica gel has no smell or no taste, chemically inert material with its higher surface area with a porous structure which is able to absorb enormous quantities of moisture. The practicality of white gel is non-indicating when it is free from moisture, it goes to transparent white, without any change in its shape and size.
Dehumidifier which reduces the level of the dew point of humidity in the surfacing air with the use of silica gel white beds to eliminate odour, mould, and mildew in the household appliances which are grown inside.

Orange Silica Gel Beads
Silica gel orange is enriched with an organic indicator which offers orange colour to silica gel. It is used for moisture absorption on an industrial level.
It has no side effects in the environment and is safe for health because of its organic nature and also it is non-toxic. When it becomes moisture free, the colour of orange beads turns from dark green to black. Like blue silica gel, orange silica gel is also an indication.

Blue Silica Gel Beads
Silica gel blue is a semi-transparent glassy substance that contains an indicator called As the beads take up moisture, they turn to light blue gradually and then they turn pink, it indicates that the gel needs to be replaced or regenerated. In fact, it is mainly used as an indicator for the extent of dehumidification and moisture adsorption in a sealed vessel. Silica gel is available in the form of crystals and beads according to the user’s application.
