Nano Aerogel Felt
The green and environmentally friendly silica aerogel felt is a nano-level porous insulation material prepared by evenly loading nano-silica aerogel onto a fiber matrix. This material has excellent thermal insulation properties and is currently the world’s most advanced solid thermal insulation material. Compared with traditional insulation materials, aerogel felt has significant advantages in insulation performance, water resistance, flexibility, and ease of installation. The main benefits include:
1.Ultra-low Thermal Conductivity, Excellent Thermal Insulation Performance, and Long Lifespan
The aerogel’s unique nanoporous network structure effectively blocks heat transfer through solid conduction, convective heat transfer, and radiation heat transfer, significantly improving insulation performance. It has superior insulation effects, reducing energy consumption while extending the lifespan of insulation layers. Compared to traditional materials, aerogel insulation can achieve the same insulation effect with a much thinner thickness, greatly reducing insulation space and improving efficiency.
2.Hydrophobic and Moisture-Resistant
With a water repellency rate of ≥99%, the material prevents the absorption of moisture, avoiding the negative effects of water vapor on insulation performance. It also prevents condensation and corrosion, enhancing the durability of insulation materials.
3. Excellent Fire Resistance
Aerogel felt is non-flammable, safe, and reliable, effectively reducing fire hazards.
4.High Flexibility and Easy Installation
The material can be cut and installed on-site according to actual needs, making it suitable for complex piping and equipment insulation applications.
5.Light Weight, Cost Reduction
The aerogel felt has a low density and high flexibility, making it easy to install. It reduces labor costs and overall project expenses, helping to lower installation and maintenance costs.
6.Excellent Durability
The material is resistant to extreme weather conditions and maintains stable performance over long-term use. It remains effective even under high temperatures and humid environments.
7.Environmental Safety
The material is non-toxic, does not release harmful substances, and is an environmentally friendly insulation choice.

How to Apply Aerogel Felt
1. Preparation
Select the Right Type: Choose the appropriate thickness and specifications based on the insulation needs (e.g., pipes, tanks, walls).
Gather Tools & Materials:
- Utility knife or scissors
- Measuring tape
- Adhesive or fastening tape
- Safety gloves and mask (to prevent inhaling fine dust)
Ensure a Clean Surface: The surface where the aerogel felt will be applied should be clean, dry, and free of dust or grease for optimal adhesion.
2. Cutting & Shaping
Measure & Cut: Use a measuring tape to determine the required dimensions and cut the aerogel felt accordingly using a sharp knife or scissors.
Avoid Waste: Minimize unnecessary cuts and overlaps to reduce material waste.
3. Application Methods
For Pipes & Tubes
- Wrap the aerogel felt around the pipe, ensuring a snug fit.
- Secure it with high-temperature-resistant adhesive, tape, or metal wire.
- For better protection, use an outer protective layer such as aluminum foil or PVC wrapping.
For Flat Surfaces (Walls, Panels, Tanks, etc.)
- Lay the aerogel felt onto the surface.
- Attach it using industrial adhesive, mechanical fasteners, or insulation pins.
- Seal the edges with tape or additional insulation layers to prevent heat leaks.
For Complex Shapes & Equipment
- Cut the felt into custom shapes to fit curved or irregular surfaces.
- Secure it in place with adhesive, tape, or clamping bands.
4. Sealing & Finishing
Seal the Joints: Overlapping seams should be sealed with high-temperature adhesive tape to prevent heat loss and moisture penetration.
Use a Protective Layer (Optional): In high-impact areas or extreme weather conditions, cover the aerogel felt with aluminum foil, metal sheets, or weather-resistant coatings for added durability.
5. Inspection & Maintenance
Check for Gaps or Loose Areas: Ensure there are no gaps that could cause heat loss.
Regular Inspection: Periodically check for damage, moisture accumulation, or wear, especially in industrial settings.
Replace Damaged Sections: If any part of the insulation becomes damaged, replace or repair it to maintain effectiveness.
Application Areas
- Industrial pipelines and processing equipment
- Oil & gas pipelines
- HVAC ducts and refrigeration systems
- Automotive and aerospace components
- Building insulation for walls, roofs, and floors
By following these steps, aerogel felt can provide long-lasting, high-performance insulation, reducing energy costs and improving safety.
