Orange silica gel


Orange silica gel is the indicating silica gel which changes its color from orange to pink or green when it takes up moisture. Its main component is silicon dioxide and it is now rapidly replace blue silica gel because of its non-toxic, odorless, harmless, enviroment safe.
Orange silica gel is an environmentally safer alternative to traditional blue indicating silica gel, which contains cobalt chloride. It turns from orange to nearly clear when it has become saturated.

Application:
1. Orange silica gel indicator can be used alone or be mixed with other silica gel. To dry and indicate the humidity, we can place appropriate amount of the goods in appropriate containers or packaging to achieve this purpose.
2. Protection of moisture damage to your precision instruments, pharmaceuticals, petrochemicals, food, clothing, leather, home appliances and other industrial gases, etc. It can also be used for domestic purposes such as moisture proofing and dehumidifying.
Sizes: 1-3mm, 2-4mm, 2-5mm, 3-5mm, 4-8mm.
Packing: 25KG/bag,500KG/bag, Plastic bag, Compound bag, One Ton/bag.
