Export Color-Variable Silica Gel

Detailed Product Description


Characteristics
The European Union decided in 1998 that cobalt chloride is a carcinogen and blue silica gel containing cobalt chloride was thus prohibited and disappeared from European and American markets. To meet the needs of the market, our Company developed color-variable silica gel. In the form of spherical or irregularly-shaped grains, the gel is currently presented either purple, orange or yellow. 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, and its color varies as humidity changes.

Technical Data
   Put proper amounts in a suitable container or package and set the container or package where drying or humidity indication is needed. This gel can be used independently or in combination with other types of silica gel. After changing color as a result of absorbing dampness, the gel can be reused after heating to change back to its pre-use color. Heating is most suitable between 100-120.
