Aerogel is highly fire-resistant but not completely fireproof. It has exceptional insulating properties, including thermal insulation, which makes it effective in withstanding high temperatures for a significant period. However, extreme and sustained exposure to fire can eventually cause damage to aerogel.
Aerogel is a lightweight material composed of 90-99% air, with the remaining portion made up of a solid network of interconnected particles. This unique structure gives aerogel its remarkable insulating properties. When exposed to fire, aerogel initially prevents heat transfer and acts as a barrier. It can withstand temperatures up to 1,200 degrees Celsius (2,192 degrees Fahrenheit) without significant structural damage.
While aerogel is highly resistant to flames and has a high ignition point, it can eventually break down and lose its insulating properties when exposed to extremely high temperatures or prolonged fire exposure. The exact performance will depend on the specific composition and manufacturing process of the aerogel.
It's worth noting that aerogel is used in various applications where fire resistance is desired, such as in insulation for high-temperature industrial equipment or in protective clothing for firefighters. However, in situations with intense or sustained fire, additional fireproofing measures are usually necessary to ensure complete protection.
