Orange Silica Gel Indicator

【NAME】Orange Silica Gel Indicator
【COMPOSITION】
Its main component 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.
Its molecular formula is: SiO2 + H2O + C25H30CLN3
【PERFORMANCE AND USAGE】
In 1998, the European Union has identified the cobalt chloride as carcinogens in the second category. Blue silica gel with cobalt chloride in Europe and the United States has been banning to produce, and it has a tendency to be eliminated gradually. In order to adapt to market’s needs, our company developed orange silica gel without cobalt chloride.
The product 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.
This product 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 obviously according to the hygroscopic capacity. So it’s often called "humidity indicator."
