Silica aerogel has an even lower thermal conductivity. If you seek the ultimate in thermal insulation performance, silica is the better choice. Silica aerogel is lighter and thinner than ceramic fiber, and it is flexible and bendable. It is more advisable for applications with compact structures, weight restrictions, and complex geometries. However, ceramic fiber can withstand higher temperatures, up to approximately 1400℃.
Silica aerogel insulation materials can be used in new energy vehicle battery systems for applications such as cell insulation layers, inter-module thermal barriers, battery casing insulation, and thermal runaway protection layers. They enhance battery safety by preventing and delaying heat propagation while maintaining optimal operating temperatures.

What is Silica Aerogel Insulation？
Silica aerogel is an extremely lightweight, nanoporous solid material made from silica. Due to its exceptionally high porosity (approximately 90%–99%), extremely low density, and minimal thermal conductivity, it effectively blocks heat transfer, serving as an excellent thermal insulator.
Additionally, its outstanding high-temperature resistance makes it a valuable fireproofing material that enhances safety. You can use it in new energy vehicles, battery systems, industrial equipment, fire protection engineering, and more.
Types of Silica Aerogel Insulation
Silica Aerogel Blanket
Aerogel blanket is a composite material made by bonding silica aerogel insulation with glass fiber or nonwoven fabric. It is very flexible, easily cut and die-cut to shape, and simple to install. Its bendable nature allows it to provide thermal protection for complex structures. Applications include batteries, high-temperature equipment housings, industrial piping, storage tanks, and buildings.
Silica Aerogel Panel
Unlike aerogel blankets, aerogel panels are rigid or semi-rigid boards manufactured by compressing silica aerogel insulation material. They offer high hardness and mechanical stability, primarily serving as thermal insulation for large flat structures. If you’re seeking suitable thermal insulation materials for building envelopes or similar applications, they provide an excellent solution.
Composite Silica Aerogel Materials
Composite silica aerogel materials are easy to process and can be effectively laminated with glass fiber, aluminum foil, EMI shielding layers, and other substrates to form insulation materials with additional specific functions. The resulting silica aerogel composites are better suited for mass production. They offer enhanced functionality while reducing product footprint and lowering costs.
Functions of Silica Aerogel Insulation
Thermal Insulation
On one hand, the high porosity of silica aerogel insulation creates a void-filled structure with an extremely low thermal conductivity. On the other hand, it impedes heat transfer by suppressing solid heat transfer, inhibiting gas convection, and reducing radiative heat transfer. It has a lower thermal conductivity than materials such as asbestos, fiberglass, and polyurethane foam, achieving higher thermal insulation efficiency. This can reduce heat loss or block heat ingress.
High-Temperature Protection
Silica aerogel insulation not only help to thermal insulation but also has outstanding high-temperature resistance. Depending on the specific model, its maximum operating temperature ranges from approximately 200°C to 650°C. Consequently, it serves as a high-temperature protective material, shielding temperature-sensitive components such as batteries and pipelines from damage.
For instance, it can be incorporated into equipment housings to reduce surface temperatures, preventing overheating that could lead to electrical hazards.
Fireproof and Flame-Retardant
Silica aerogel insulation is an inorganic material with ultra-high stability in flames. It neither burns nor melts, and does not produce harmful substances when exposed to fire. Consequently, it can be used in construction as a fireproof layer to impede flame spread and heat transfer.
It can also be applied within battery cells, modules, and casings in new energy vehicles and energy storage equipment to provide fire protection, prevent severe consequences from fires, and enhance safety.
Energy Saving
Silica aerogel insulation reduces heat loss and enhances thermal performance in industrial piping and storage tanks, buildings, batteries, and energy storage systems, thereby decreasing cooling system loads. This conserves energy consumption, lowering operational costs over extended periods.
Additionally, silica aerogel insulation is very lightweight, reducing weight burdens and minimizing energy consumption in automotive, transportation, and aerospace applications.
How Does Silica Aerogel Insulation Work?
Suppressing Thermal Conductivity in Solids
Silica aerogel insulation consists of a porous network of micron-sized silica particles filled with tiny voids. Its porosity reaches 90–99%, with the voids filled with air. Its solid pathways are not only sparse but also have minimal surface area. Consequently, it struggles to form efficient heat transfer pathways, hindering heat transfer within the solid material.
Suppress Convection
Although silica aerogel has a large number of voids, the pore size of these voids is extremely small, preventing air molecules from flowing efficiently within them. This hinders air convection, preventing the formation of effective heat transfer pathways and making heat transfer between air layers difficult. So the thermal conductivity of silica aerogel remains extremely low, ranging from approximately 0.013 to 0.018 W/m·K.
Reduce Heat Radiation
Silica aerogel insulation typically has infrared blocking agents and can scatter infrared radiation structurally, preventing heat dissipation through thermal radiation in high-temperature environments. Consequently, silica aerogels maintain exceptional thermal insulation properties even under extreme heat conditions. It is advisable for you to use them in industrial equipment, EV battery thermal protection, and similar applications.
