White Silica Gel

Narrow pore white silica gel is colorless or slightly yellow transparent glassy in substance. It is mainly used as desiccants, moisture absorbents and rust inhibitors, and can protect instruments, weaponry, electronic equipment, medicine, foodstuff, textile products and other packed material from moisture. It can also be used as a carrier of catalysis and the dehydrating refinement of organic products. Because of its high packing density and effective moisture absorption under low humidity, it is used for the purification of air, drying of garments and nappies, and in cooling systems for energy saving. The desiccant can remove moisture from the air to control the humidity. Also it is often used in ocean shipment to keep goods from the damage caused by excessive humidity; or between tightly sealed double window to maintain the transparency of the window by removing the moisture inside.
