Silica Gel Blue 500gm 20 per Carton

500gm Blue Indicating Silica Gel Desiccant Bag (Code: DSGB500)

Protect enclosed machinery, cargo, electronics, and large storage containers from humidity and condensation with Silica Gel Direct's 500gm Blue Indicating Desiccant Bags. Engineered in a durable composite non-woven pillow bag, this heavy-duty moisture absorber combines high-capacity desiccant beads with a dynamic visual indicator that changes from blue to pink as it becomes saturated.

Key Benefits & Features

• Clear Visual Saturation Indicator: The indicating beads change dynamically from blue to pink, giving you an immediate visual cue when the bag has reached maximum absorption capacity and needs replacement or reactivation.

• Heavy-Duty Non-Woven Fabric: Sealed in a tough PET/PE/PP composite non-woven pillow bag designed for high tear resistance, zero linting, and optimal air permeability.

• High-Capacity Moisture Absorption: Rapidly absorbs moisture from enclosed spaces, taking on ≥9% of its weight at 20% RH, ≥23% at 50% RH, and up to ≥34% at 90% RH (tested at 25°C).

• Non-Corrosive & Leak-Proof: Holds absorbed moisture trapped safely within the bead structure purely through physical adsorption. Remains dry to the touch even when fully saturated, leaving no liquid residue or corrosive by-products.

• Bulk Master Carton Packaging: Packed 20 bags per carton inside a double HDPE plastic bag liner with a Humidity Indicator Card (HIC) to ensure maximum freshness during transit and storage.
