Blue Indicating Silica Gel Loose Pack 250gm regulates moisture levels through high-porosity silicon dioxide granules. Within airtight containers, these beads absorb up to 40% of their own weight in water vapor. Upon reaching saturation, an integrated cobalt chloride indicator shifts the bead color from blue to pink.
Key Features
- Visual Color Indicator: Cobalt Chloride additive changes from blue to pink. It signals saturation levels during humidity control.
- Regenerable Material: Silicon Dioxide beads withstand temperatures between 100-145°C. Heating the pink granules restores the blue state.
- High Absorption Capacity: Porous granules trap moisture up to 40% of their mass. This prevents mold on lenses during road dust exposure.
- Loose Granule Form: 250g of silicon dioxide beads in a flexible pack. It fills custom dry boxes for corrosion protection.
Frequently Asked Questions
How to reactivate blue silica gel?
Heat the granules at 100-145°C in an oven until the blue color returns. This process drives out absorbed moisture to make the desiccant reusable.
Is blue silica gel toxic?
The cobalt chloride indicator makes this material toxic if swallowed or inhaled. Keep it away from food and use it only for equipment moisture control.
