Silica Gel Beads
Silica gel is a type of reusable desiccant that adsorbs moisture and lowers humidity in enclosed spaces preventing the formation of mould, condensation and rust. It is odourless, non-toxic, non-corrosive, and chemically inert. During adsorption, silica gel beads remain dry and retain their size and shape.
Silica gel is available in non-indicating and indicating varieties. Indicating silica gel changes colour to show when it has reached its capacity for moisture adsorption and requires replacement or reactivation.
It is used in a broad range of commercial and industrial applications including: transformer breathers, compressed air systems, electrical boxes, mining, aerospace and laboratories.
We offer all these particle sizes: 1-3 mm, 2-4 mm, and 3-5 mm.
All our silica gel beads are tested and certified to meet global export standards, Our silica gel desiccant products comply with REACH and RoHS standards, and we can provide SGS product test reports, halogen and sulfur element test reports, and MSDS chemical composition reports.

Blue Silica Gel Beads
(1-3 mm, 2-4 mm, 3-5 mm) Available
Blue silica gel turns pink as it adsorbs moisture, indicating the need for reactivation or replacement. Prevents the formation of mould, condensation and rust in enclosed spaces.
- Beads contain blue to pink moisture indicator
- Lowers relative humidity to approximately 35-40%
- Helps prevent mold, condensation and rust
- Remains dry when saturated with moisture
- Reusable
- Inert and non-toxic
- Non-corrosive
Blue indicating silica gel is ideal in applications where visual control of moisture is required. The silica gel will turn from blue to pink as it adsorbs moisture, indicating the need for reactivation or replacement. Silica gel works by adsorbing and trapping moisture from the air, lowering humidity and preventing the formation of mould, condensation, and rust in enclosed spaces.
Silica gel's high surface area allows it to adsorb up to 35%-40% of its weight in moisture while remaining dry to the touch. It is inert, non-toxic and has the ability to be reactivated multiple times. Silica gel will remove moisture at temperatures as high as 60°C, but it is best used at room temperature (20-35°C) and high relative humidity (60-90% RH).
When silica gel turns pink, reactivate as follows:
Spread silica gel on a tray and place in an oven at 115°C to 125°C for approximately 2-3 hours or until beads turn blue again. Once the silica gel has been reactivated, remove from the oven and let cool until able to handle. Store silica gel in a sealed container until ready to use.
Orange Silica Gel Beads
(1-3 mm, 2-4 mm, 3-5 mm) Available
Orange silica gel turns green as it adsorbs moisture, indicating the need for reactivation or replacement. Prevents the formation of mould, condensation and rust in enclosed spaces.
- Beads contain orange to green moisture indicator
- Lowers relative humidity to approximately 35-40%
- Helps prevent mold, condensation and rust
- Remains dry when saturated with moisture
- Reusable
- Inert and non-toxic
- Non-corrosive

White Silica Gel Beads
(1-3 mm, 2-4 mm, 3-5 mm) Available
White non-indicating silica gel prevents the formation of mould, condensation and rust in enclosed spaces by adsorbing excess moisture. (Does not contain a moisture indicator.)
- Lowers relative humidity to approximately 35-40%
- Helps prevent mold, condensation and rust
- Remains dry when saturated with moisture
- Reusable
- Inert and non-toxic
- Non-corrosive
