With the continuous development of science and technology, the requirements for thermal insulation materials in all walks of life are becoming higher and higher. In this context, the new thermal insulation material aerogel gradually received people's attention and use. Aerogel has become a kind of eye-catching material because of its unique structure and properties. So, what are the characteristics of aerogel?

One of the most important features of aerogel is its ultra-low density. While traditional insulation materials tend to be heavy, up to more than 90% of the composition of aerogel is air, which makes it one of the lightest solid materials in the world. This lightweight characteristic not only makes aerogels more convenient in transportation and installation, but also shows great application potential in aerospace, automotive lightweight and other fields.

In addition to its lightness, aerogel is also known for its excellent thermal insulation properties. The nanoscale porous structure within it effectively prevents heat conduction, resulting in a low thermal conductivity of the aerogel (0.012 ~ 0.024W/(m·K)). Studies have shown that the same thickness of aerogel compared with traditional insulation materials, its insulation performance can be increased by 3 to 5 times. This makes aerogels an energy-efficient insulation material that can stay warm in winter and cool in summer.

In addition, aerogel also has good chemical stability and weather resistance. It is able to maintain stability under various extreme environments and chemical corrosion, and will not reduce thermal insulation performance due to long-term use. This feature enables aerogels to continue to play their thermal insulation role in long-term use and reduce energy waste.

In addition to low density, low thermal conductivity and chemical stability, aerogel also has earthquake resistance, fire resistance, durability and sound absorption. These characteristics make aerogel an ideal multi-functional material, which is widely used in construction, industry, transportation and other fields.
