Product Description

Industrial Silica Gel Orange to Green Indicating Desiccant 2-4mm for Drying Type A
Description:
The main component of orange silica gel is silicon dioxide and its color varies with the humidity. With the exception of blue silica gel's performance, it also has characters of cobalt chloride free, non-toxic, odorless, harmless, etc.
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, normally called "humidity indicator."

Application:
The 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.
