Type C Silica Gel Desiccant Manufacturers

This Type C silica gel desiccant is a transparent or translucent macroporous silica gel. It is a hygroscopic material with physical adsorption, silicon dioxide as the main component.

Noted: We can custom desiccant for specific applications.

Mechanical Strength	≥90%
Particle Size	1–3 mm / 2–5 mm
Applications	Gas drying, catalyst support,etc.

Advantages of Type C Silica Gel Desiccant

Fast adsorption, high mechanical strength, but lower moisture capacity than Type A/B. Best for low-humidity or high-pressure applications.

Macroporous Structure

Large Pore Size: 8-10 nm average diameter, significantly wider than Type A (2-3 nm) and Type B (4-7 nm) silica gels
Highly Interconnected Pore Network: enabling rapid diffusion of gases and liquids
Moderate Surface Area: 200-350 m²/g; lower than finer-pored variants, but optimized for fast kinetics

Key Advantages

Superior Mass Transfer: ideal for applications requiring quick adsorption/desorption (gas drying, catalysis,etc.)
Enhanced Mechanical Stability: robust pore structure withstands pressure better than microporous types

Physical Properties

1. Appearance

Transparent or translucent glass-like particles
Spherical or irregular shape without cracks

2. Mechanical Properties

High mechanical strength (crush resistance ≥ 90%)
Good wear resistance, suitable for dynamic adsorption system

Applications

Application Fields	Typical Use Cases	Key Advantages
Gas Drying	Compressed air systems, industrial gas purification(natural gas, N₂),moisture prevention of air compressor	Fast adsorption, high-pressure resistance, excellent mechanical strength
Catalysis & Chemical	Catalyst supports (e.g., petrochemical reactions), macromolecular adsorption	Macroporous structure enhances diffusion, high thermal stability
Protective Packaging	Moisture-proofing for precise instrument,electronics, military equipment storage	Rapid moisture capture, non-corrosive (neutral pH)
Industrial Filtration	Pre-treatment of high-temperature/dusty gases (e.g., flue gas)	Thermal resistance (-40°C-200°C), dust erosion resistance
Dynamic Adsorption	Adsorption devices that require frequent regeneration cycles,such as Pressure Swing Adsorption (PSA) systems	High mechanical strength, crush-resistant
