Type A Silica Gel

Fine Pore Silica Gel is another name for A-type Silica Gel. Type A silica gel is an absorbent, which is a dried gel of the combination of silicon oxide with water. It is produced as a colorless large granular particles with a finely porous structure.

Properties: Type A silica gel has a highly porous structure with a large absorbent surface area. It has strong adsorption under low humidity and is suitable as general desiccants. It is inert to other compounds, and has a good mechanical resistance to crushing and abrasion. Insoluble in organic and water-based solvents.

Through our silica gel customisation service we are able to supply these materials and to fine-tune their properties.

Application:

Fined pored silica gel is often used to regulate the relative humidity of the air for the storage and transportation of equipment, leather, luggage, apparel, food, medication, and other items.It is actively used in industry production. Silica gel effectively removes moisture, and is also used for absorption and purification of industrial gaseous substances and oils. Applied for drying high humidity locations as well as the air entering the compressors
