blue silica gel for desiccant DMF free

Product Overview

Description

blue silica gel 

   Silica Gel is a granular, porous form of silica made synthetically from sodium silicate, Despite the name, silica gel is a solid and the highest capacity adsorbent available today.

 

Characteristic:

1, High security: no harm or poison for human beings and Non-toxic and tasteless;

2, Excellent Absorption ability: as high as 34%

3, It is insolvable in water/any solvents;

4, High absorbability and good packing material.

5, Good thermal stability;

6, Stable chemical properties, not with any physical reaction eliminated alkali and hydrofluoric acid, strong mechanical strength;

7, Good heat stability, It is also called dehumanize as a solid material in adsorb or absorb water vapor.

 

Usage:

1, Prevent the articles going mould or corrosion and rust;

2, widely use in shoes and cap, bags, furniture, toy, hardware, gift, wooden products.

3,  Safe to use to protect foods, medicine, sensitive materials and much more. Even when saturated with adsorbed moisture, silica gel looks and feels dry to the touch.

 

Storage:

Keep dry.
