USE: 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.

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 theUnited Stateshas 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.
Orange silica gel has a strong capacity of absorption moisture. Therefore it should be stored in a dry place, with shelves or pallets between the ground and the goods. Packaging Material has steel drum, paper can, carton, plastic bottle, polyethylene plastic compound bag, flexible container bags, etc. During transportation, it should keep away from the rain, the damp and exposure.
