Specification: 

Blue silica gel includes blue indicating silica gel,color-changing silica gel and blue silica gel. Blue silica gel has the appearance of the blue or light blue glass-like particles, according to the shape of particles It can be divided into spherical ones and block ones. Meanwhile, It has a property of turning pink from blue after absorption.

Notes:  Blue Silica gel contains a touch of Cobalt chlorides. In terms of the shape, It has two different kinds- the spheric and loaf shape. When in absorbing the moisture, its color will change from blue into purple and finally into reddish. In this way, it clearly shows the humidity of the surrounding environment; at the same time let us know if it can be still moisture-proof.

Use:

1.Mainly used for moisture absorption and rust proofing when instruments and equipment are placed in obturation conditions, at the same time, according to their own color turning red from blue after the moisture absorption it can indicates ambient humidity directly.

2.It being used with ordinary silica gel desiccant, we can get the desiccant moisture level and judge the relative ambient humidity.

3.Desiccant silica gel used for packaging, it is widely used in precise instruments, leather, shoes, clothing, food, medicine and household appliances, etc.

Product description:

Silica gel desiccant is a highly active adsorption material.It is usually made of reacting with sodium 

silicate an sulfuric acid, aging as well as acid bubble.

It is insoluble in water and any solvents.Non-poisonous and tasteless, chemical stability.

It won't react with any material except alkli and hydrofluoric acid.

 tandard white silica gel is referred to as being non-indicating. As absorbs moisture it remains  physically unchanged. Non-indicating silica gel is both cheap and effective, available  loose in bulk  packs or packed in sachets.

Application:

Applied to package of shoes,garment,furniture,Military Use,Container,Electronic products,leather-wear,art ware,gift box, Jewel box,tea leaf box etc.

Feature:

1. It will adsorb up to 34%of its own weight in water vapour. This adsorption efficiency is approximately 3

greater than typical desiccant clays, making silica gel the preferred choice where weight or efficiency are 

important factors.

2. It has an almost indefinite shelf life if stored in airtight conditions.

3. It can be regenerated and reused if required. Gently heating silica gel will drive off the adsorbed 

moisture and leave it ready for reuse.

4. It is a very inert material, it will not normally attack or corrode other materials and with the exception 

of strong alkalis and hydrofluoric acid is itself resistant to attack.

5. It is non-flammable.

6. It is most frequently and conveniently used packed in a breathable sachet or bag. These are available in a wide range of sizes suitable for use with a wide range of applications.
