TS-DS700 series nanoporous rolls are a kind of flexible insulation blankets composed of nanoporous silica aerogel and inorganic fiber materials through the fiber reinforcement process. Nanoporous silica has special nanoscale three-dimensional porous structure, high specific surface area and large porosity. The composite nanoporous insulation materials have excellent characteristics such as ultralow thermal conductivity, small density, overall hydrophobicity, high-temperature stability, flame retardancy (Class A), sound insulation and noise reduction, and are safe, energy-saving and environmentally friendly.
