Advantages of Aerogel Felt

Argentina's Rosario Grain Exchange recently reported that wheat Aerogel Felt, Aerogel Felt Overview, Aerogel Felt Application, Aerogel Felt Supplier, Aerogel Felt Price are expected to continue to be influenced by international situations.

Aerogel Felt Overview

Aerogel felt is a flexible thermal insulation felt made of nano-silica or metal aerogel as the main material, which is compounded with carbon fiber or ceramic glass fiber wool or pre-oxidized fiber felt through a special process. It is characterized by low thermal conductivity, certain tensile and compressive strength, and belongs to a new type of pipeline insulation material.

Aerogel felt has the lowest thermal conductivity of solid thermal insulation materials in the temperature range of 400 °C (the thermal conductivity in the high temperature region of 400-1000 °C is much higher than that of the micro-nano thermal insulation series).

Aerogel felt has the characteristics of softness, easy cutting, low density, inorganic fire resistance, overall hydrophobicity, and environmental protection. It can replace glass fiber products, asbestos insulation felt, silicate fiber products and other traditional flexible thermal insulation materials that are not environmentally friendly and have poor thermal insulation performance.

Advantages of Aerogel Felt

1. Excellent thermal insulation effect

The thermal insulation effect of aerogel felt is 2-5 times that of traditional thermal insulation materials. According to the Arrhenius experiment, the theoretical high-temperature pipeline service life is close to 20 years.

2. Reduce the thickness of the insulation layer

Aerogel felt achieves the same thermal insulation effect and is only a fraction of the thickness of traditional materials. After insulation, the heat loss is small and the space utilization rate is high. And at high temperature, the above performance advantages are more obvious.

3. Hydrophobicity and fire resistance

Aerogel felt is relatively hydrophobic, which can effectively prevent moisture from entering pipes and equipment. At the same time, it has B1 to A-level fire resistance, and the unique three-dimensional network structure of aerogel avoids the obvious decline of other thermal insulation materials such as sintering deformation and settlement during long-term high-temperature use.

4. Convenient construction

Aerogel felt is lightweight, easy to cut and sew to fit various shapes of pipes and equipment insulation, and requires less time and labor to install.

5. Save on shipping costs

Smaller package size and lighter weight can greatly reduce the transportation cost of insulation materials.

Application of Aerogel Felt

Nano aerogel felt is a material with excellent thermal insulation properties. Its pore size is smaller than the mean free path of air molecules under normal pressure. Therefore, the air molecules in the aerogel voids are approximately stationary, thereby avoiding the convective heat transfer and condensation of the air. The extremely low bulk density of the glue and the tortuous paths of the nanomesh structure also prevent heat conduction from gases and solids, and the empty walls minimize thermal radiation. These three aspects work together to block almost all heat transfer methods. The aerogel achieves the thermal insulation effect that other materials cannot match, and is even far lower than the thermal conductivity of a few air at room temperature of 0.025W/mK, reaching below 0.018W/mK.

Aerogel felt is mainly used in industrial pipelines, storage tanks, industrial furnaces, power plants, rescue cabins, warship bulkheads, automobiles, directly buried pipelines, injection molding machines, removable insulating sleeves, high-temperature steam pipelines for heavy oil extraction, and transportation. , home appliances, steel, non-ferrous metals, glass and other thermal insulation fields.

Degree: 1~20mm

Width: about 1.5 meters

Density: 160~240kg/m³

Applicable temperature: -200℃~1000℃ (specific product related)

Hydrophobicity: There are two kinds of hydrophilic and hydrophobic (specific product related)

Thermal conductivity: 0.02~0.1W/(m·k) (specific product related)

1. Low temperature and high temperature resistance:

-200℃~+650℃, excellent performance in extreme hot and humid environment up to 650ºC.

2. The thermal insulation performance is 3 times that of traditional thermal insulation products.

Low thermal conductivity, at room temperature: about 0.02 w/(m*k).

3. More and wider space utilization

Due to the low thermal conductivity, the same insulating effect can be achieved with a thinner insulating thickness.

4. Safe and non-combustible (smoke-free), Class A

The combustion performance grade meets the requirements of the combustion performance grade specified in GB8624-2012, and the fire protection grade is Class A.

5. Green and environmentally friendly

Chlorine-free and halogen-free, it can be used for landfill disposal, and the surface dust is polycrystalline aerogel powder.

6. Flexible, lightweight and easy to install

It is easy to cut, not easy to deform, and has little loss, which is especially beneficial to installation. Disassembly is also simple, reducing downtime during regular maintenance and eliminating the need to purchase replacement insulation.

7. Hydrophobic and breathable

The water increase rate is 99%, but the steam can be discharged, making the equipment drier and longer. Enhanced corrosion protection under insulation for longer service life.


The U.S. Department of Energy has launched a $3.16 billion program to improve the supply chain for electric vehicle batteries. 

The U.S. Department of Energy recently announced on its website that it will receive $3.16 billion from the bipartisan infrastructure bill to develop domestic electric vehicle battery manufacturing in the United States. $3.1 billion will be invested in new, retrofitted, and expanded facilities related to electric vehicle batteries, and $60 million will be spent on recycling and reuse of used batteries.
