Detailed Product Description

Characteristics.

The European Union decided in 1998 that cobalt chloride is 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 produced 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 varied as humidity changs.

After changing colof as a result of absorbing dampness,the gel can be reused after heating to chang back to its pre-use color. Heating is most suitable between 100-120 ^.C.
