Type A silica gel is a transparent or translucent particle with a chemical molecular formula mSiO2.nH2O. It is insoluble in water and inorganic acids, soluble in hydrofluoric acid and strong caustic soda solutions. This silica gel exhibits high mechanical strength and good wear resistance.
It is primarily used for drying and moisture-proofing applications. Additionally, it can serve as catalyst carriers, adsorbents, separators, and variable-pressure adsorbents.

Discover high-quality blue silica gel packets from Lianyungang Chemsize. Available in 2.0kg or 500kg bags. Ideal for moisture control and protection.
Blue silica gel consists 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. This desiccant can be used alone or with Type A Silica Gel.
Primarily used for absorbing moisture and preventing rust in enclosed conditions. When it absorbs moisture, it changes color from blue to red, visually showing the relative humidity. When used with ordinary silica gel or a drier, it helps determine the moisture absorption level and relative humidity. Ideal for packing precision instruments, leather goods, shoes, clothing, food items, medicines, and household appliances.

Product Name: Type C Silica Gel Variable-Pressure Adsorbents
Description: Cobalt-free color-changing silica gel for effective 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, derived from blue gum color-changing silica gel, is now available in an orange variant. It is made from fine porous silica gel infused with an inorganic salt mixture and utilizes non-toxic compound dyes to eliminate environmental pollution caused by traditional dyes and discoloration agents. With its original technological conditions and excellent adsorption performance, this product represents a new generation of environmentally friendly solutions.
Primarily used as a desiccant and indicator of desiccant saturation levels, this silica gel is ideal for sealing packaging and monitoring relative humidity in precision instruments and general packaging to prevent moisture damage.
