Silica gel desiccant is made of high-quality silica gel raw materials. After multiple steps of screening to ensure each silica gel particle is clean and dust-free.The moisture absorption is stable and its moisture absorption speed is fast. The adsorption rate is as high as 35%. The silica gel desiccant can be reused by drying at high temperature after absorbing moisture.
Blue indicating beads are dark blue when dry and turn pink when saturated. This type is commonly used in compressed air and gas drying applications. 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.
0.5gram and 1gram silica gel desiccant are most popular for rapid test kits used. And silica gel desiccant can use in diferrent fileds such as food/medical/garment/furniture/shoes/electronics etc..
