Indicating silica gel stands out among desiccants due to its unique chemical treatment, facilitating a color transition as it absorbs moisture from the surrounding environment. This distinctive feature aids users in recognizing when it's time to replace or recharge the desiccant.
Indicating silica gel undergoes a color change, unlike non-indicating desiccants, making it easier to gauge moisture absorption levels. There are two main types: Orange Indicating Silica Gel and Blue Indicating Silica Gel.
Orange Indicating silica gel initially appears orange or yellow when dry and transitions to green when saturated with moisture, indicating the need for replacement. It's non-toxic, eco-friendly, and widely used in various sectors, including compressed air dryers, transformer breathers, and flower and seed preservation.
Precaution: Keep Orange silica gel away from consumable products and medications.
Applications of Orange Indicating Silica Gel:
Blue Indicating Silica Gel, treated with concentrated cobalt chloride, changes from blue to pink when saturated with moisture. While it shares similar applications with Orange Silica Gel, it's less accessible due to restrictions in the European Union because of cobalt's potential toxicity.
Precaution: Keep Blue Silica Gel away from consumables and medications.
Applications of Blue Indicating Silica Gel:
Conclusion:
Silica gel beads, available in various sizes and shapes, offer high absorption power suitable for professional and industrial use.
