Blue Silica Gel Desiccant in bags of 200kg or 500kg by Lianyungang Chemsize. Cobalt-free, aluminum-based, and color-changing for effective moisture absorption.
Blue silica gel is composed of blue or light blue glassy particles. It can change color from blue to purple and finally to light pink as it absorbs moisture, indicating the humidity level of the environment. This product can be used as a desiccant on its own or in combination with Type A Silica Gel.
Blue silica gel is primarily used for absorbing moisture and preventing rust in instruments, gauges, and equipment kept in enclosed conditions. When it absorbs moisture, it changes color from blue to red, visually showing the relative humidity of the surroundings. When used with ordinary silica gel or a drier, it helps determine the extent of moisture absorption and assess the relative humidity of the environment. This product is commonly used as a silica gel drier for packing precision instruments, leathers, shoes, clothes, foodstuffs, medicines, and household electric appliances.
