Orange silica gel often called “humidity indicator” 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.
Orange silica gel has a strong capacity of absorption moisture. During the process of absorption moisture, the appearance of the
color changes to green obviously according to the hygroscopic capacity.
