Aerogel Is One Of The World's Smallest Solid Density
Aerogel is one of the world's smallest solid density
(1) aerogel profiles
Aerogel is one of the world's smallest solid density, the density is only 2.75 times as the density of the air, known as "blue smoke". Aerogel insulation blanket is high temperature resistant and aslo can withstand 1200 degrees.
Aerogels are nanostructured porous materials with low thermal conductivity, low refractive index, low elastic modulus, low density, low impedance, high temperature resistance, flame retardancy and so on.
Joda aerogel thermal insulation blankets mat, aerogel insulation board, aerogel powder products can be used in aerospace, heating / cooling, oil / gas, LNG, chemical, construction, transportation, metallurgy, electronics, environmental protection and other fields.
(2) Aerogels properties
|specific surface area||The specific surface area is generally between 200~1000m2/g|
|porosity||Average pore diameter 50nm|
|Compressive force||Aerogels have very good compressive properties in comparison with micro molecule foams and fiber insulators|
|Hydrophobicity||The hydrophobic material will be infinitely hydrophobic and can be pressurized up to 5MPa in hydrostatic pressure to prevent water seepage|
|Acoustic performance||Sound speed at 100m/s, very low propagation sound performance, if added fiber,it will greatly improve the sound insulation|
|Refractive properties||Having an ultra-low refractive index (1.025) near the air|
|Dielectric constant||Having an ultra low solid dielectric constant (<1.1)|
|toxicity||Aerogels are amorphous silicone gels that are safe and harmless|
