Our Orange Silica Gel is not impregnated with cobalt chloride, it is the latest product that can replace the blue silica gel indicator. The composite dyeing agent without pollution to the environment has been successfully adopted during the manufacturing process of the orange silica gel indicator. In this way, it has prevent the cobalt chloride from polluting the environment from the very beginning.
There are two types with the orange silica gel indicator. One is Orange – Dark green Type, it discolors from orange into dark green during the process of moisture adsorption; another is Orange - Colourless Type ,it discolors from orange into light green when adsorbing moisture. Both the orange silica gel indicators have much more adsorption capacity than that of the blue Indicating silica gel. The orange silica gel Indicator has won unprecedented
acknowledgement and praise from the clients since its introduction in European and American markets.
