Silica gel desiccant is a highly useful variety of desiccant, available in a range of mesh sizes to meet the
needs of its many possible uses in industry. It does not react with chemicals, and is tasteless, odorless, non-toxic, and
non-corrosive. It is extremely porous and can adsorb a large amount of water due to its vast amount of internal surface area.Since it is non-deliquescent, its size and shape always remain the same, and there are no chemical reactions or byproducts thatresult from the adsorption process. Even when saturated with water, the gel stays free-flowing, and dry. What makes blue indicating silica gel particularly useful is that, as it adsorbs water, it changes color, going from blue to purple to pink as the moisture is adsorbed.

White Silica Gel
(1) it can be used for bottled medicines and foodstuffs. It is sure to keep the goods dry and prevent miscellaneous mildew growth.
(2) it can be used as packing disccant and used it for moisture-proof.
(3) Silica gel for packing has many different packing sizes. It can be conveniently put into the packing of various articles( for
example, instruments and gauges, electronical products, leathers, shoes, food ,stuffs, medicines and householdelectric appliances,etc.) in order to keep the articles from damp, mildew or rust corrosion.
Blue Silica Gel
Color-Variable Silica Gel
1: In the form of spherical or irregularly-shaped grains, the gel is currently presented purple, orange or yellow.
2:With silicon dioxide as the chief ingredient, the product performs all the functions of blue silica gel but does not contain
cobalt chloride and is therefore innocuous and pollution-free,
3:Its color varies as humidity changes.

Orange silica Gel
The product can be used alone or be mixed with other silica gel.To dry and indicate the humidity, we can place appropriate amount of the goods in appropriate containers or packaging to achieve this purpose.
This product is mainly used for drying, instructing the degree of drying or humidity, and widely used in precision instruments,pharmaceuticals, petrochemicals, food, clothing, leather, home appliances and other industrial gases, etc. It can also be used fordomestic purposes such as moisture proofing and dehumidifying.
Orange silica gel has a strong capacity of absorption moisture. During the process of absorption moisture, the appearance of the color changes obviously according to the hygroscopic capacity. So it's often called "humidity indicator.
