Discover our High Bulk Density Silica Gel Beads available in 20kg or 500kg bags. The blue silica gel from Lianyungang Chemsize International Trading Co., Ltd. is a premium quality desiccant for efficient moisture absorption.
Blue silica gel consists of blue or light blue glassy particles. The product is available as blue silica gel indicator and blue silica gel. It is known for its hygroscopicity process, turning from blue to purple and eventually to light pink as it absorbs moisture. This color change indicates the humidity level of the environment and signals when a replacement desiccant is needed. Blue silica gel can be used independently as a desiccant or in conjunction 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. As it absorbs moisture, it changes color from blue to red, visually displaying the relative humidity of the environment. When used with ordinary silica gel or a drier, it helps gauge the moisture absorption level and determine the relative humidity of the surroundings. This product is widely employed as a silica gel drier for packaging precision instruments, leathers, shoes, clothes, foodstuffs, medicines, household electric appliances, and more.

High Bulk Density Silica Gel Beads in sizes of 1-3mm, 2-4mm, and 3-5mm. Cobalt-free, color-changing, and packed in 25kg bags. Ideal for moisture absorption.
The European Union classified cobalt chloride as a Class II carcinogen in 1998, leading to the ban of blue gum containing cobalt chloride in Europe and the United States. To address market demands, cobalt-free environmental discoloration silica gel was developed.
This product is based on blue gum color-changing silica gel but uses non-toxic compound dyes to eliminate environmental pollution caused by dyes and discoloration agents. It retains its original technological conditions and offers excellent adsorption performance, making it a new generation of environmentally friendly products.
The cobalt-free environmental discoloration silica gel is primarily used as a desiccant and indicating desiccant saturation degree in sealed packaging. It is suitable for maintaining the relative humidity of space medium in precision instruments, general packaging, and instruments vulnerable to moisture.
