Aerogel felt is a new type of thermal insulation material made of aerogel and reinforced fiber. For new materials, in order to understand it well, understanding its parameters is essential. So what are the parameters of aerogel felt?

1. Thermal conductivity
The thermal conductivity of aerogel felt is an important parameter. Thermal conductivity is an index to measure the heat transfer capacity of a material, which determines the efficiency of the material in the heat preservation process. The thermal conductivity of aerogel felt is usually between 0.015 and 0.025W/(m·k) at room temperature, which means that it has a very low thermal conductivity, which can effectively slow down the transfer of heat, so as to achieve a good insulation effect.

2. Thickness and width
The thickness of the aerogel felt is also a parameter to be considered. The thickness determines the number of insulation layers and the insulation effect of the material. Generally speaking, the thickness of the aerogel felt can be selected between 1 and 20mm, and the specific thickness is determined according to the actual needs and application scenarios. Thicker insulation can provide better insulation, but it will also increase the amount of material used and the cost. Generally speaking, the width of the aerogel felt is about 1.2~1.5m, which can be convenient for construction and installation and improve construction efficiency.

3. Density
The density of aerogel felt is also an important parameter. Density determines the weight and volume of the material. The density of aerogel felt is usually between 160 and 240kg/m³, which makes it a great advantage in the field of insulation, which can reduce the weight of the building and reduce energy consumption.

4. Temperature range
The applicable temperature range of aerogel felt is also a parameter that needs to be considered. Different application scenarios have different requirements for the high temperature resistance of materials. The applicable temperature range of aerogel felt is usually between -200 ° C and 1000 ° C, which makes it possible to maintain stable insulation performance in a variety of harsh environments.

5. Tensile strength
Tensile strength is also one of the parameters to be considered. In PASCAL (Pa) as a unit, the tensile strength reflects the resistance of the material under tensile stress, and is directly related to the service life and reliability of the material. In general, the compressive strength of aerogel felt is usually between 0.1 and 5MPa.
As a new kind of thermal insulation material, the parameters of aerogel felt include physical properties, thermal insulation properties, temperature resistance properties and other characteristics. The optimization and design of these parameters enable aerogel felt to give full play to its excellent insulation effect and performance in various fields.
