Detail

Properties:

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 grains, the color change is from Orange to Green. 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.


Application:

Mainly for drying and indicating humidity of precision instruments, medicine, petrol chemicals, foodstuff, clothing, leather, electric appliances, other industrial gases, etc.

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.
