Characteristics:Â
The European Union decided in ***8 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.Â
Use:Â
Mainly for drying and indicating humidity of precision instruments,
medicine, petrol chemicals, foodstuff, clothing, leather, electric
appliances, other industrial gases, etc.
 Â
Technical Data:Â
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 ******0º
