As a top super thermal insulation material, aerogel is widely used in petrochemical, metallurgy, aerospace and other high-temperature fields. Currently, a common selection misunderstanding prevails in the industry: many buyers and engineering teams only refer to short-term room-temperature thermal conductivity when choosing aerogel, which brings severe hidden dangers to energy conservation, operational safety and project costs. Aerogel’s excellent insulation comes from its nano-porous structure. Most products show good short-term thermal conductivity at room temperature, but this index only reflects the initial performance. Under actual industrial conditions including continuous high temperature, thermal cycling, vibration and corrosion, inferior aerogel will suffer pore collapse, sintering and pulverization, resulting in a sharp decline in insulation performance. Experts point out that six core indicators should be taken into account, such as long-term thermal stability and thermal shock resistance. For high-temperature aerogel, stable long-term performance is far more important than low initial thermal conductivity. The industry suggests evaluating products from a full life-cycle perspective to avoid selection risks. https://www.tiktok.com/@mia_iota/video/7597717976720149782
