Water Resistant Silica Gel: FNG Silica Gel for Air Separation, Compressed Air Drying & Catalyst Carrier
Created on 08.26
Introduction: When Ordinary Silica Gel Meets Water, FNG Silica Gel Keeps Its Shape
Silica gel is one of the most widely used desiccants in the world. But in certain industrial processes—especially those involving liquid water, high humidity, or repeated regeneration—ordinary silica gel can break down, lose its shape, and require frequent replacement.
Water Resistant Silica Gel, also known as FNG silica gel, is engineered to solve this problem. Processed and formed from powders into pellets, it retains the adsorption properties of ordinary silica gel while adding good water-resistant property, low breakage rate, high regeneration efficiency, and long service life.
Whether you are drying air in an air separation plant, adsorbing acetylene in liquefied air preparation, or drying compressed air and industrial gases, FNG silica gel delivers reliable, long-lasting performance.
What Is Water Resistant Silica Gel (FNG Silica Gel)?
Water resistant silica gel is a pellet-shaped desiccant with a white or light gray color. It is processed and formed from powders, giving it a dense and durable structure.
Key features:
- Shape: pellets
- Color: white or light gray
- Processed and formed from powders
- Good water-resistant property
- Low breakage rate
- High regeneration efficiency
- Long service life
- High compression strength
- Non-breaking ratio in water ≥ 90%
Unlike ordinary silica gel, FNG silica gel maintains its shape and mechanical strength even when exposed to liquid water or repeated regeneration cycles. This makes it ideal for demanding industrial applications.

Main Applications
1. Drying in Air Separating Process
Water resistant silica gel is mainly used for drying in the air separating process. Its high mechanical strength and water-resistant property allow it to withstand the demanding conditions of air separation plants.
2. Adsorption of Acetylene in Liquefied Air and Liquefied Oxygen Preparation
It is used for the adsorption of acetylene in the preparation of liquefied air and liquefied oxygen. This is a critical safety application, as acetylene can accumulate and create hazards if not properly removed.
3. Drying Compressed Air and Various Industrial Gases
FNG silica gel is used for drying compressed air and various industrial gases. Its high adsorption capacity and long service life reduce downtime and replacement costs.
4. Petrochemical, Electric Power, and Brewing Industries
In the petrochemical industry, electric power industry, brewing industry, and other industries, it is used as a liquid adsorbent and catalyst carrier.
5. Buffer Desiccant and Silica Sand
It may also be used as the buffer desiccant and silica sand for ordinary silica protective beds.
FNG-I vs. FNG-II: Which One to Choose?
Property | FNG-I | FNG-II |
Bulk density, g/L | 600–700 | 400–500 |
Compression strength, N/particle ≥ | 80 | 80 |
Non-breaking ratio in water, % ≥ | 90 | 90 |
Typical use | Higher density applications | Lower density applications |
Both grades offer excellent water resistance and mechanical strength. The choice between FNG-I and FNG-II depends on your specific bulk density requirements and equipment design. Our technical team can help you select the right grade.
