Aerogel insulators produced by PANDA IRogel Company, in addition to their excellent thermal and cryogenic insulation properties, also have sound, moisture and electrical insulation properties:
moisture insulation
Silica aerogel is a nanoporous material with a very high specific surface area of more than 600 m2/gr. More than 95% porosity has made it the lightest commercial material in the world. The cavities are filled with air with an average size of 20 nanometers. In superhydrophobic aerogels, the entire surface of the material is covered with special functional groups that cause water to be expelled from their surface at a contact angle of more than 150°. In other words, the presence of cavities filled with air and functional groups together, creates a superhydrophobic property for silica aerogels, which causes a very long life of these insulators compared to other hydrophilic insulators. Conventional insulators get wet during the day and night by absorbing condensate and lose their initial performance in a short time. During the day, the air is warm and the relative humidity of the air increases, and at night, as the temperature decreases, the humidity condenses and is absorbed on the hydrophilic insulation. Super-hydrophobic aerogel insulators maintain their performance up to more than 300 °C. Aerogel blanks are also superhydrophobic like aerogel granules and in addition to their surface, all internal parts are also superhydrophobic.
Sound insulation
Due to the adverse effects and consequences of noise pollution in natural and human environments, the need to control it is seriously raised. In order to deal with this problem, there are various methods. The use of nanoporous materials as sound insulation is one of these methods. Sound waves are absorbed and attenuated when they come in contact with porous materials. The higher the porosity of the sound insulation, it will have more absorption power. Sound insulators based on nanoporous aerogels have very high porosity and very high specific surface area and can absorb more than 3 times the energy of sound waves with a thickness of 1 cm and reduce the speed of sound. This means that by installing aerogel thermal insulation, moisture and sound insulation properties are created at the same time. In various cases such as ambient noise, process equipment noise and etc. aerogel insulation can reduce noise pollution.
Electrical insulation
Silica material and a very low density of 0.003 to 0.2 gr/m3, makes aerogel products completely electrically insulating.
