1-3mm 2-5mm Silica Gel Desiccant Moisture Absorber for Electronic Chemical

Silica gel, mainly composed of amorphous silica, transparent or white irregular granular or spherical solid. It has an open porous structure and strong adsorptivity. It can adsorb a variety of substances and is a high-performance active adsorbent. We choose high-quality Paohua Alkali to eliminate your worries. It is non-toxic, tasteless, and chemically stable. It does not react with any substance except strong alkali.Silica gel has adsorption capacity under various conditions.
 

We supply 3 types of ordinary silica gel as desiccant.

Type-A White Silica Gel also called Type A Silica Gel, it is fine-pored spherical silica gel ,which are transparent or semitransparent glasslike in appearance.

 

Type-B(Blue Silica Gel) and Type C (Orange Silica Gel) is desiccant with humidity indicating function. After absorbing moisture, it change color, visually indicating the relative humidity of the given environments. When being used with ordinary silica gel or drier, it indicates to which extent the drier absorbs the moisture and judges the relative humidity of a given environment. It is widely used as silica gel drier for the packing of the precision instruments, leathers, shoes, clothes, foodstuffs, medicines and household electric appliances…etc.

 

Beside bulk bag packing, we can produce 0.5-2000g pure white or mixed silica gel packets, accept combine shipment of all grades.

The desiccant must be in a relatively sealed environment to play the role of moisture absorption. The better the package sealing is, the better the desiccant effect is. In case of poor sealing, please increase the dosage
