Orange silica gel

Indicating Orange Silica Gel:
Orange silica gel is an indicator silica gel bead that changes its color from orange to pink or green when it absorbs moisture. Silica gradually changes color from orange in the activated state to green in the saturated state. It can be reactivated by heating to 250-450°F in clean air until it turns orange again. The gel is naturally orange in color with active activity and a saturation level of 6 %.
Since it is non-toxic, odourless, safe for the environment, and has silicon dioxide as its principal component, it is quickly replacing blue silica gel.
Orange silica gel is an environmentally friendly alternative to traditional blue indicating silica gel that contains cobalt chloride. It turns from orange to almost transparent when it becomes saturated.

Desiccant Orange Silica Gel:
Orange silica gel beads are an environmentally friendly, non-toxic desiccant that can absorb 40% of its own weight in water. We offer orange silica that turns yellowish when saturated because there are no visible physical changes when ordinary silica is saturated. Beads fulfill the requirements of ecologically aware businesses. Orange silica gel has many applications where visual control of moisture is required, such as compressed air dryers, respirators, protecting non-consumable packaged goods, drying and storing flowers and seeds, etc.Today, orange silica gel is the most popular type of silica gel utilized in commercial applications.

Note: The value of qualified ratio of spherical granules is just applicable to the qualified ratio of silica gel spherical granule.

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.

Note: The moisture content, packing and size can be adjusted according to customer’s different requirements

Sizes: 1-3mm, 2-4mm, 2-5mm, 3-5mm, 4-8mm.

Packing: 25KG/bag,500KG/bag, Plastic bag, Compound bag, One Ton/bag.
