ORANGE SILICA GEL has a strong capacity of absorption moisture. During the process of absorption moisture, the appearance of the color changes obviously according to the hygroscopic capacity. So it’s often called "humidity indicator."

Orange Silica Gel Application:

1. Orange silica gel 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. Orange silica gel is mainly used for drying, instructing the degree of drying or humidity, and widely used in 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.
