Blue silica gel
Characteristics :
Color-Variable Silica Gel
1: In the form of spherical or irregularly-shaped grains, the gel is currently presented purple, orange or yellow.
2:With silicon dioxide as the chief ingredient, the product performs all the functions of blue silica gel but does not contain cobalt chloride and is therefore innocuous and pollution-free,
3:Its color varies as humidity changes.
Use: Mainly for drying and indicating humidity of precision instruments, medicine, petrol chemicals, foodstuff, clothing, leather.
Size :1-3mm,2-4mm,3-5mm,4-8mm
Packag: 25kg compound bag or 25kg drum, special packing as requirements.
1. Used for absorbing moisture of instruments, gauges and equipment in the enclosed conditions.
2. After adsorb moisture, it turns blue into red, visually indicating the relative humidity of the given environment..
3. When being used with ordinary silica gel or drier, it indicates to which extent the drier absorbs the moistures and judges the relative humidity of a given environment.
4. Used to judge if the humidity of a environment is up to the specified requirements and to determine if the adsorbent or drier ceases to be effective.

Orange Silica Gel
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
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."
PRODUCT SPECIFICATION:1-3mm, 2-4mm, 2-5mm, 3-5mm, 4-8mm
PACKAGING MATERIAL:25KG/bag,500KG/bag, Plastic bag, Compound bag, One Ton/bag.
PACKAGING AND STORAGE:
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.
