Aerogel blanket and glass wool are both Class A non-combustible materials and have excellent fire resistance and fire resistance. However, the maximum operating temperature of aerogel blanket is 1400°C, which is higher than the 538°C of glass wool. The thermal conductivity of aerogel is 0.017(w/m.k)/25℃, and that of glass wool is 0.033~0.040(w/m.k)/25℃. Therefore, aerogel blanket has more advantages than glass wool in terms of thermal insulation performance.
The maximum operating temperature of rock wool is 800°C, and the thermal conductivity is 0.037~0.043(w/m.k)/25°C. Therefore, the aerogel blanket has better high temperature resistance and thermal insulation performance. In addition, the density of aerogel blanket is very small, only 3 kilograms per cubic meter, and the density of rock wool is 80-200KG per cubic meter, so the load of rock wool is heavier.
The operating temperature of rubber and plastic is -40~105°C. It is a B1 and B2 grade material with a thermal conductivity of about 0.034w/m·k. Therefore, it is not as good as aerogel in terms of high temperature resistance and thermal insulation performance. Rubber plastic, like aerogel, is dust-free and lightweight, and its waterproof performance is better than rock wool and glass wool.
