Aerogel sheet products are a kind of rigid, hydrophobic, high temperature resistant, fire-retardant, powder-free, heat-insulating and heat-insulating sheet made by compounding nano-porous aerogel with inorganic fiber materials using a special process.The special process makes the aerogel board products have extremely low thermal conductivity, low density, excellent overall hydrophobic performance, fireproof and flame retardant grade up to A1 standard, no powder shedding during transportation and use, green and environmentally friendly, and at the same time it has superior sound insulation, noise reduction, anti-compression and shock absorption characteristics.
