Product Description
Silica Gel Blue is a self-indicating, high-quality desiccant composed of amorphous silicon dioxide. It contains a moisture-sensitive cobalt chloride indicator, which gives it a blue color when dry and changes to pink when saturated with moisture. This property makes it ideal for monitoring humidity levels in packaging, storage, and industrial processes.
Widely used for moisture control, drying, and humidity indication, Silica Gel Blue is highly effective in protecting products, equipment, and sensitive materials from moisture damage.
