Transparent or translucent glass-like beads or irregular granules.
Product Description:
Fine-pored Silica Gel (Type A) is a high-performance microporous adsorbent mainly composed of silicon dioxide (SiO₂). With an average pore diameter of 2–3 nm and a large specific surface area, it offers excellent moisture adsorption, particularly under low humidity conditions. It is widely used for industrial drying, gas purification, moisture control, catalyst support, and the dehydration and purification of organic compounds.
Features:
High bulk density
Excellent moisture adsorption under low humidity conditions
Large specific surface area
High mechanical strength
Good abrasion resistance (spherical beads provide superior wear resistance)
Insoluble in water and most inorganic acids
Soluble in hydrofluoric acid and concentrated alkali solutions
Regenerable through heating
Stable chemical properties
Suitable for repeated adsorption and regeneration cycles
Advantages:
High adsorption efficiency at low relative humidity
Long service life
Excellent mechanical durability
Low dust generation
Easy regeneration and reuse
Reliable performance in a wide range of industrial applications
Applications:
Drying and moisture protection for industrial gases and compressed air
Air purification and humidity control
Catalyst carrier in chemical processing
Dehydration and purification of organic compounds
Moisture protection for pharmaceuticals, instruments, textiles and electronic products
Moisture control in food packaging and storage
Oil refining and petrochemical processing
Adsorbent for refrigeration and freezing systems
Cargo protection during sea transportation
