Silica Aerogel Insulation Board

Description:

Silica aerogel insulation board is a high-dispersion solid material that has colloidal particles aggregated into a nanoporous network structure, and the gap is filled with a gaseous dispersion medium. Its porosity can reach 80~99.8%, the pore size is generally between 1~70nm, and its density is as light as only 2.75 times the density of air, which is unmatched by other insulation materials in the field of insulation in the world today.

Silica aerogel insulation board has excellent properties such as low thermal conductivity, high temperature resistance, flame retardancy, low density, and low acoustic impedance. At the same time, it also has strong water resistance and long service life. In aerospace, national defense, communications, medical, petroleum, chemical, minerals, rail transit, ships, new energy, nuclear power, construction, environmental protection, and automobiles, there are very broad application prospects.

Physical properties:

Packaging form: roll

Thickness: 5mm, 8mm, 10mm

Width: 1500mm

Density: 180-220kg/m3

Applicable temperature: -200℃——+1000℃ (related to the model)

Hydrophobicity: Absolutely hydrophobic (below 350°C)

Thermal conductivity: 0.012-0.018w/m·k (at 25℃)

Advantages:

1. Service life

According to the Arrhenius experiment, the theoretical service life is 20 years, which is almost the same as the life of the building.

2. Reduce the thickness of the insulation layer

Silica aerogel insulation board achieves the same thermal insulation effect, and its thickness is only a fraction of that of traditional materials. After heat preservation, the heat loss is small and the space utilization rate is high. And at high temperatures, the above performance advantages are more obvious.

3. Hydrophobicity and fire resistance

Silica aerogel insulation board is absolutely water-repellent, which can effectively prevent water from entering the pipeline and equipment. At the same time, it has building fire protection performance, and the unique three-dimensional network structure of aerogel avoids the obvious reduction of heat preservation effects such as sintering deformation and sedimentation of other heat preservation materials during long-term high temperature use.

4. Convenient construction

Silica aerogel insulation board is light in weight, easy to cut and sew to adapt to various shapes of pipes and equipment for heat preservation, and it requires less time and labor for installation.

5. Save transportation costs

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