Aluminum foil ceramic fiber board is an inorganic composite material board with excellent performance. The board is mainly composed of two inorganic materials, ceramic fiber and aluminum foil, and has significant inorganic material properties. From the perspective of material composition, ceramic fiber, as the core component, is a fibrous lightweight refractory material with alumina (Al₂O₃) and silicon dioxide (SiO₂) as the main components. Its inorganic non-metallic properties give the board excellent thermal properties. Aluminum foil is used as the surface layer material, and its metal aluminum (Al) component further strengthens the inorganic properties of the board. This unique combination of materials makes aluminum foil ceramic fiberboard fully meet the definition standards of inorganic materials.
In terms of performance, aluminum foil ceramic fiberboard fully integrates the advantages of the two components. Ceramic fiber contributes excellent high temperature resistance (usually can withstand high temperatures above 1000℃), extremely low thermal conductivity (about 0.05-0.15W/(m·K)), excellent thermal stability and excellent resistance to mechanical vibration. The aluminum foil layer provides good radiant heat reflection performance and air tightness, while enhancing the structural integrity of the board. This synergistic effect makes the board outstanding in fire prevention (can reach Class A non-combustible standard), thermal insulation (thermal conductivity as low as 0.035W/(m·K)), and heat preservation.
Based on these excellent physical and chemical properties, aluminum foil ceramic fiberboard is widely used in industrial high-temperature equipment insulation (such as petrochemical pipelines, boilers, etc.), building fire isolation (firewalls, fire door core materials), ship cabin insulation, and aerospace. Its inorganic nature ensures long-term stability in various harsh environments, and will not cause common aging and decomposition problems of organic materials. The service life is significantly better than that of organic insulation materials. With the continuous improvement of modern industry's requirements for fire safety, the application prospects of this inorganic composite board will be broader.
