H.S No.:2811220000


Molecular Formula: O2Si


Molecular Weight: 60.08


Melting point:1625

Usage:
1.Mainly used for absorbing moisture, anti-rusting of instruments, gauges and equipment in the enclosed conditions. After absorbing moisture, it turns from blue to red, visually indicating the relative humidity of the given environments.
2.When being used with ordinary silica gel or drier, it indicates to which extent the drier absorbs the moisture and judges the relative humidity of a given environment.
