5.5 LBS Orange Silica Gel Desiccant Beads, Reusable & Color Indicating Premium Desiccant Bulk, Industry Standard 3-5 mm Silica Beads for 3D Filament, Camera, Jewelry, Safe (10PC Organza Bag)

High Absorption Capacity: Silica gel beads are safe, cobalt chloride-free, and deliver outstanding moisture absorption. They can soak up to 35% of their own weight, efficiently pulling moisture from enclosed storage spaces to shield items from damage.
Rechargeable: These reusable desiccant beads can be refreshed by heating them in an oven for 0.5 to 2 hours at 200 to 250°F, or in a microwave for 7-10 minutes at 700W, until all beads turn bright orange. Depending on the state of the silica beads, it may take less time than recommended; check the bead color periodically.
Color Indication: The orange silica gel shifts to green when 50-60% saturated with moisture. The first color change does not mean full saturation; the desiccant keeps absorbing moisture until reaching 50-60% RH and then turns dark green.
Package Contents: The package contains 10 organza bags and 5.5 lbs of rechargeable desiccants, sealed in an airtight barrel for extended preservation and protection. The bead size is the industry standard of 3-5 mm and is not suitable for drying flowers.
Wide Application: Color-changing desiccant can be broadly used in daily life. Employ it to effectively prevent moisture damage to 3D printer filament, electronic devices, cameras, documents, jewelry, gun safes, clothes, and many other valuables.
Industry Standard Size: Features 3-5mm beads that meet industry standards, appropriate for use in various containers including air compressor systems, safes, toolboxes, weapons cases, and storage areas requiring moisture control.
Safe Formula: Made with 100% orange silica gel that is entirely free of cobalt chloride, ensuring safe use around your valuable items including electronics, precision instruments, photo equipment, and important documents
