Silica Gel Blue is a desiccant, or drying agent, that manufacturers often place in little packets to keep moisture from damaging certain food and commercial products.

• Product Name: Silica Gel
• Granular Size: 2.5mm
• Pack Size: 25 Kg Bag
• Color: Blue
• Origin: China

Silica Gel Blue 25 Kg Bag is a commercial-grade, moisture-indicating desiccant composed of a highly porous, granular form of silicon dioxide . Impregnated with cobalt chloride as a chemical indicator, this bulk desiccant changes color from deep blue to light pink as it saturates with water vapor. This provides a visual cue that the media has reached its high adsorption threshold (up to 40% of its dry structural weight) and requires replacement or thermal regeneration

• Industrial Dehumidification: Placed inside electrical transformer breathers, heavy generator switchgears, and CNC control boxes to absorb airborne humidity and prevent terminal short-circuiting.
• Logistics & Machinery Preservation: Packed inside bulk export shipping containers to protect automotive assemblies, metallic machinery, and dynamic electronics from container rain or surface oxidation.
• Laboratory Air Desiccation: Ideal for filling desiccant columns, gas-drying towers, and sealed laboratory vacuum desiccators.
