White Silicagel

Silicagel is one of the widest used adsorption agents against moisture with a wide range of applications. It consists of irregularly shaped and porous particles and is a form of silicic acid. The raw materials are mostly sodium silicate and sulphuric acid. Silica gel is inert, odourless, non-toxic and non-corrosive. The large inner pore surface allows adsorption up to approx. 36 % of its own weight. It is available as white or indicator gel.

Silica Gel White is also known as Non-Indicating White Silica Gel as it remains unchanged in appearance on adsorbing moisture. White Silica Gel is in the form of ivory-white semi-transparent round vitreous body or crystals with good absorption capacity but we cannot determine whether Silica gel has completely absorbed moisture or not. It has been confirmed that White Silica Gel causes no odor, toxin and pollution and is one of the most widely used damp proof agent in the world.

Light type Silica Gel with much larger average pore diameter and pore volume has exceptionally high absorption capacity at very high relative humidity only, it is not normally used as a desiccant but since it withstands liquid contact without fraction it is used as a guard material to remove entrained liquids from gas streams.
