Silica gel desiccant is a type of drying agent or moisture absorber that is commonly used to control humidity and prevent moisture damage in various industries. It is made from silica dioxide, a naturally occurring mineral that has a highly porous structure capable of adsorbing water molecules from the air.
Silica gel desiccant is typically available in small packets or sachets and is used to protect products and materials from moisture during storage and transportation. It is commonly used in the electronics, pharmaceutical, textile, and food packaging industries, among others.
Silica gel desiccant is highly effective at absorbing moisture from the atmosphere, with some products capable of adsorbing up to 40% of its weight in water vapor at 25°C and 100% relative humidity. It is also safe to use, non-toxic, and environmentally friendly. Silica gel desiccant is easy to install and remove, and requires minimal maintenance or monitoring.
Overall, silica gel desiccant is an effective and cost-efficient way to prevent moisture damage during transportation and storage of goods, helping to preserve product quality, reduce waste, and increase sustainability.
Blue indicating beads are deep cobalt blue when dry and turn pink when saturated. This type is commonly used in compressed air and gas drying applications, as well as for tank breathers. The color indicator is cobalt-chloride, a carcinogen. Blue indicating silica gel should be avoid in food, pharmaceutical, and other applications where human ingestion may occur.
Orange indicating beads are best for applications where color change is desired and the material may be exposed to food or medicine. These beads turn light green when saturated.
White non-indicating silica gel beads contain no color indicator Typical applications include humidity control in packages and containers and moisture control in safes, closets, and other spaces. White silica gel is less expensive than indicating types and may be mixed with either blue or orange types to achieve humidity indication.
