Product Description

Product Description

Cobalt-Free Environmental Discoloration Silica Gel

Product Description

Properties

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 replaced with orange color-changing silica gel. 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 dyes and discoloration agents. With its original technological conditions and excellent adsorption performance, it has become a new generation of environmentally friendly products.

Application

This silica gel 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 space medium in precision instruments, general packaging, and instruments vulnerable to moisture.

Blue Silica Gel Product Description

Welcome to Lianyungang Chemsize International Trading Co., Ltd.

Blue Silica Gel

Blue silica gel is an excellent primary desiccant that can also be blended with other desiccants for applications requiring visual moisture control. Chemsize silica gel beads are saturated with a moisture-indicating solution, turning deep blue when dry and changing color as it adsorbs moisture.

Features:

• Chemical Formula: SiO₂·nH₂O + CoCl₂


• Narrow pore silica gel with interconnecting pores of 20-30 nanometers


• Effective moisture removal up to 220°F, best used at room temperature and high relative humidity

Typical Applications:

• Compressed air dryers


• Gas drying


• Breathers


• Packaged goods

Type A Silica Gel

Type A silica gel is a transparent or translucent particle with high mechanical strength and good wear resistance. It is insoluble in water and inorganic acids, soluble in hydrofluoric acid and strong caustic soda solutions.

Specifications:

• Chemical Formula: mSiO₂·nH₂O


• Average pore diameter: 2.0-3.0nm


• Surface Area: 650-800m²/g


• Pore Volume: 0.35-0.45ml/g

Applications:

Mainly used for drying and moistureproof, as well as catalyst carriers, adsorbents, separators, and variable-pressure adsorbents.
