MGO Board For Building Materials Fireproof Magnesium Oxide Board

Magnesium oxide fireproof board, commonly known as MGO Board in the industry, is a new type of inorganic building board made from natural mineral magnesium oxide as the core base material, magnesium sulfate (or magnesium chloride) aqueous solution as the setting medium, mixed with glass fiber, plant fiber or industrial solid waste fillers and other reinforcing components, through modern processes such as precise proportioning, high-pressure molding and natural curing. This board is not a simple improvement of traditional building materials, but a multi-functional integrated material developed based on the natural endowments of magnesium oxide minerals and combined with the diverse needs of contemporary buildings for safety, environmental protection and durability. Although its application history is only a few decades, the application of magnesium oxide, the core base material, in the construction field can be traced back to ancient times. This mineral component was once incorporated into the masonry mortar of the Great Wall of China, which fully demonstrates the historical accumulation of its stable performance.

Advantage of MGO Board for Building Materials Fireproof Magnesium Oxide Board

Fireproof Performance - Core Safety Barrier for BuildingsFire resistance is MGO Board's key advantage. It's fireproof not because of added chemical flame retardants, but because of magnesium oxide's own inorganic properties. Tests show it can stand extreme high temperatures up to 1200℃, is completely non-combustible with no flame spread. It meets ASTM E136 non-combustible standards and China's Class A fire rating-zero flame spread and zero smoke. In real buildings, depending on thickness and installation, it can resist fire for 2-4 hours, way better than traditional materials like gypsum boards. Even when roasted at high temperatures for a long time, it won't release toxic gases like formaldehyde or heavy metals, buying crucial time for evacuation and property protection. Big landmarks like Taipei 101 and large subway stations use it for walls and fire partitions.

Weather Resistance & Durability - Works in All ScenariosMGO Board's stability in harsh environments (humidity, corrosion) breaks the limits of traditional building materials. Its water absorption is under 12%-even in humid places like southern China, underground garages or cold chain warehouses, it won't expand, delaminate or get moldy. It's also termite and insect resistant, fixing the problems of wood boards rotting and fiber cement boards cracking. Physically, it's strong: compressive strength over 30MPa, flexural strength over 8MPa, density 1.1-1.4g/cm³-light but strong. It reduces building load, resists daily impacts, and stays stable. Even with big temperature/humidity changes, it barely expands (less than 0.06‰) and won't deform or crack.

Green & Eco-Friendly - Sustainable for Dual Carbon GoalsAs green buildings become more popular, MGO Board's eco-advantages stand out. Its production doesn't need high-temperature sintering, using 40% less energy than traditional ceramics and cement. It can also use over 30% industrial waste (like desulfurized gypsum, slag powder). In 2022, national production used 960,000 tons of solid waste, cutting CO2 equivalent by 1.27 million tons. The board has no formaldehyde, asbestos or VOCs, meeting GB/T 27630-2023 green building material standards. It has no odor and won't hurt indoor air quality, perfect for hospitals, schools and homes that need high eco-standards.
