Orange Silica Gel has been accepted as the perfect substitute for the indicating type blue silica gel as it is impregnated with an organic indicator. With silicon dioxide as the main ingredient it has all the properties of blue silica gel but does not contains cobalt chloride. The composite dyeing agent without pollution to the environment has been successfully adopted during the manufacturing process of the orange silica gel.
When in dry state the particles are dark orange in appearance, as the particles take up moisture the colour gradually changes from orange to dark green thereby indicating that Silica Gel has adsorbed moisture and requires immediate replacement or regeneration. The orange silica gel has won unprecedented acknowledgment and praise from the clients since its commercial introduction into the markets.
