Discover our Blue Silica Gel Beads in 2.0kg or 500kg bags for efficient moisture control. Ideal for minimizing loss and ensuring safe, long-term moisture absorption.
Blue silica gel consists of blue or light blue glassy particles, categorized into blue silica gel indicator and blue silica gel. It changes color from blue to purple to light pink as it absorbs moisture, indicating humidity levels and the need for replacement. It can be used as a desiccant on its own or in conjunction with Type A Silica Gel.
Primarily used for absorbing moisture and preventing rust in enclosed conditions, blue silica gel transitions from blue to red as it absorbs moisture, visually displaying relative humidity levels. When used with ordinary silica gel or a drier, it helps assess moisture absorption levels and determine relative humidity. Widely utilized as a desiccant for packing precision instruments, leathers, shoes, clothes, foodstuffs, medicines, and household electric appliances.

Product Name: Color-Changing Silica Gel Beads
Size: 1-3mm, 2-4mm, 3-5mm
Packaging: 25kg Bags
Company: Lianyungang Chemsize International Trading Co., Ltd.
Description: Efficient color-changing silica gel beads for moisture control. Cobalt-free, safe, and heat-resistant desiccant.
The European Union classified cobalt chloride as a Class II carcinogen in 1998. Blue gum containing cobalt chloride has been banned 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. Orange color-changing silica gel is made from fine porous silica gel infused with an inorganic salt mixture. It utilizes new non-toxic compound dyes to eliminate environmental pollution caused by dyes and discoloration agents. With its original technological conditions and excellent adsorption performance, it has become a new generation of environmentally friendly products.
It is primarily used as a desiccant and indicator of desiccant saturation levels in sealed packaging. It is also suitable for maintaining the relative humidity of the space medium in precision instruments, general packaging, and instruments vulnerable to moisture.
