What Is Aerogel Felt

Aerogel felt is a flexible thermal insulation material made of nano silica or metal aerogel as the main body, composite glass fiber, preoxidized fiber and other reinforcement materials. Mainly used in industrial pipelines, storage tanks, power plants, new energy vehicle power batteries and other scenarios, with a suitable temperature range of -200 ℃ to 1000 ℃.
The thermal conductivity of this material is as low as 0.02~0.1W/(m · K), and its insulation efficiency is 2-5 times that of traditional materials. Under the same insulation effect, the thickness can be reduced by 50%. The product has characteristics such as B1 to A fire resistance, hydrophobicity or hydrophilicity (hydrophobicity rate ≥ 99%), lightweight and flexibility (density 160-240kg/m ³), and is easy to cut and sew to adapt to complex shapes. By using a special composite process to achieve low thermal bridging effect and tensile strength, and adopting a rolled packaging form, transportation and construction costs are significantly reduced.
Aerogel felt is a kind of flexible thermal insulation material, which is made of silica aerogel as the main material and compounded in reinforced fibers, such as glass fiber and preoxidized fiber, through special process.
Aerogel felt is the solid thermal insulation material with the lowest thermal conductivity in the temperature range of 400 ℃ (the thermal conductivity in the high temperature range of 400-1000 ℃ is much higher than that of micro nano thermal insulation series).
Aerogel felt has the characteristics of softness, easy cutting, low density, inorganic fire prevention, overall hydrophobic, green and environmental protection, which can replace the traditional flexible insulation materials with poor environmental protection and insulation performance, such as glass fiber products, asbestos insulation felt, silicate fiber products, etc.
Air gel felt is mainly used for thermal insulation of industrial pipelines, storage tanks, industrial furnace bodies, power plants, life saving cabins, warship bulkheads, motor cars, directly buried pipelines, injection molding machines, removable insulation sleeves, high-temperature steam pipelines for heavy oil exploitation, transportation, household appliances, steel, non-ferrous metals, glass and other fields.

advantage
1. Excellent insulation effect
The thermal insulation effect of aerogel felt is 2-5 times that of traditional thermal insulation materials, and the service life of theoretical high-temperature pipeline measured according to Arrhenius experiment is close to 20 years.
2. Reduce the thickness of the insulation layer
The aerogel felt has the same thermal insulation effect, and its thickness is only a fraction of that of traditional materials. Low heat loss and high space utilization after insulation. And at high temperatures, the above performance advantages are more pronounced.
3. Hydrophobicity and Fireproof
The aerogel felt is relatively hydrophobic, which can effectively prevent moisture from entering the pipeline and equipment. At the same time, it has B1 to A grade fire resistance, and the unique three-dimensional network structure of aerogel avoids the obvious decline of thermal insulation effect of other thermal insulation materials such as sintering deformation and sedimentation in long-term high-temperature use.
4. Convenient construction
The aerogel felt is light, easy to cut and sew to adapt to the insulation of pipes and equipment with different shapes, and requires less time and manpower for installation.
5. Save transportation costs
Smaller package volume and lighter weight can greatly reduce the transportation cost of insulation materials.
