Description: The main feature of Blue Silica Gel is that it has high adsorption capacity of steam in the air, and change its color from blue to purple alone with the water increasingly adsorbed.
Application field: Mainly used to indicate the saturation level and desiccant sealed packaging, precision instrument inside the space for the relative humidity, sealing packing and general instrument, etc.
