What Is The Mineral Core Aluminum Composite Panel?
Mineral Core Aluminum Composite Panel is an engineered architectural cladding material composed of two aluminum sheets bonded to a fire-retardant mineral-filled core. The panel structure consists of a front aluminum sheet, a mineral-based fire-retardant core, and a rear aluminum sheet. The mineral core is made primarily from high-purity alumina (Al₂O₃) and activated calcium oxide (CaO) through a high-temperature, high-pressure hydrothermal synthesis process. The aluminum sheets undergo surface pretreatment and coil-coating before being continuously bonded to the core through extrusion lamination or hot-press bonding, ensuring strong interlayer adhesion and long-term dimensional stability. Compared with standard PE-core ACP, the mineral core formulation significantly enhances fire performance.
Core Characteristics & Advantages
1. Enhanced fire performance
Inorganic mineral core materials such as alumina or calcium oxide are not inherently flammable, and their melting point is far above 2000°C, so they will not burn in a fire.
2. Low water absorption rate
Generally less than 5%, far lower than ordinary gypsum board (>30%), suitable for damp areas.
3. High strength and dimensional stability
Flexural strength can reach 8–12 MPa, with a small coefficient of thermal expansion, making it less prone to deformation and cracking.
4. Environmentally friendly and non-toxic
Free from asbestos, formaldehyde and other harmful substances, meeting green building material standards.
Common Applications
High-Rise and Super-Tall Buildings: Office towers, hotels, residential high-rises, mixed-use complexes, etc. for exterior facades.
High-Risk & Public Assembly Buildings: Hospitals, schools, airports, subway/transit stations, stadiums, museums, theaters.
Building Renovation & Retrofitting: Exterior recladding, energy efficiency upgrades, and aesthetic modernization of existing structures.
High-End Commercial & Interior Spaces: Shopping mall atriums, hotel lobbies, corporate showrooms, brand flagship stores.
