White Silica Gel
Non-Indicating Type Desiccant
Key Features: High moisture absorption capacity, fast absorption speed, and cost-effective. The most popular general-purpose desiccant for industrial and commercial use.
Fine Pore (Type A) Silica Gel CSG-01
Product Description
Silica gel with fine pores includes spherical silica with fine pores and massive silica with fine pores. It appears as colorless or yellow-transparent or translucent spherical particles (spherical type) and colorless or yellow translucent glass-like irregular particles (massive type).
- Average Pore Diameter: 2.0–3.0 nm
- Specific Surface Area: 650–800 m²/g
- Pore Volume: 0.35–0.45 ml/g
- Specific Heat: 0.92 KJ/kg·℃
- Thermal Conductivity: 0.63 KJ/m·Hr·℃
Applications
Fine Pore Silica Gel (Type A) is a highly effective adsorbent widely used in various industries:
- Desiccant for industrial gases (air, oxygen, hydrogen, etc.)
- Moisture-proof packaging for instruments, electronics, machinery, textiles, food, medicine, cameras, clothing, shoes, and containers
- Dehydration and refining of organic products
- Air humidity regulation
- Adsorption of flammable and explosive gases (such as acetylene) from compressed air
