Recently, with the continuous promotion of green buildings and prefabricated construction, Magnesium Oxide Board (MGO Board), as a new type of multifunctional environmentally friendly building material, has attracted widespread attention in both domestic and international markets--6.
Magnesium Oxide Board is a new type of inorganic fireproof board manufactured from lightly burned magnesium oxide, magnesium chloride or magnesium sulfate as main raw materials, mixed with reinforcing materials such as perlite, fiberglass mesh fabric, and wood fiber-6-. In terms of performance, the product features Class A1 non-combustible fire resistance, remaining non-combustible at 800℃, with no flame at 1200℃ and an ignition point as high as 2700℃-3-28; excellent water and moisture resistance, maintaining its shape without deformation after long-term immersion-3; and outstanding advantages including lightweight yet high strength (density of 0.8-1.2g/cm³, 20%-30% lighter than cement-based boards-13), sound and thermal insulation (29dB sound insulation for 6mm thick board-3), and environmental friendliness and non-toxicity (100% asbestos-free and formaldehyde-free-9)-3. The board surface is smooth and can be nailed, sawed, glued, and supports various decoration techniques including wallpapering, painting, and tile application-6.
Currently, Magnesium Oxide Board is widely applied in interior partition walls, suspended ceilings, fire door cores, and exterior wall insulation systems-. In fire-rated renovations of hospitals, schools, shopping malls, office buildings, hotels, and other public buildings, Magnesium Oxide Board has become the ideal material for wall and ceiling systems-. Additionally, the product is suitable for furniture backing panels, equipment cabinet outer packaging, and basement moisture-proof engineering-6. According to market research reports, the global Magnesium Oxide Board market reached USD 1.81 billion in 2025 and is projected to grow to USD 2.93 billion by 2034-12-13. As green building standards continue to rise, Magnesium Oxide Board is progressively becoming an indispensable new building material in modern construction.
