• What Is MGO Board? Advantages of Magnesium Oxide Boards

In modern construction and interior design, magnesium oxide board (MGO board) is emerging as a new type of eco-friendly building material gaining increasing popularity in the market. Known for its fire resistance, moisture resistance, and environmental performance, it is widely used in walls, ceilings, flooring substrates, and partition systems—especially in commercial buildings and public spaces with high fire and durability standards.

1.1 Material Composition of MGO Boards

MGO board is a composite board made primarily from magnesium oxide, combined with various fillers and reinforcing materials. Its main components include:

Magnesium Oxide (MgO): The core material, MgO offers high strength, fire resistance, and heat resistance, making it the main functional ingredient of the board.

Magnesium Chloride (MgCl₂): A gelling agent that reacts with MgO to form a hardened matrix, enhancing the structural stability of the board.

Reinforcing Fibers: Typically glass fiber mesh or natural fibers (such as wood chips or bamboo fibers) to improve tensile strength and toughness.

Fillers: Materials like perlite, fly ash, or lightweight calcium carbonate, used to reduce density, enhance insulation performance, and lower production costs.

The core chemical reaction involves MgO and MgCl₂ in an aqueous solution forming magnesium oxychloride cement (5Mg(OH)₂·MgCl₂·8H₂O), which gives the board its high strength and durability.

• Key Advantages of MGO Boards

2.1 Excellent Fire Resistance

• Made from non-combustible materials, MGO boards meet Class A1 fire resistance standards under China’s GB 50016 fire protection code.
• Heat Resistance: Can withstand temperatures up to 1000°C without burning or emitting toxic gases.
• Fire Containment: Effective as fire barrier walls or ceiling panels to prevent fire spread.
• Application Scenarios: Ideal for hospitals, schools, shopping malls, data centers, and other fire-critical environments.

2.2 Superior Moisture Resistance

• MGO boards maintain stability even in damp conditions:
• Low Water Absorption: High-quality boards absorb less than 15% water and resist swelling or deformation.
• Mold Resistance: Prevents mold growth, ideal for humid regions or basements.
• Application Scenarios: Frequently used in bathrooms, kitchens, and underground spaces.

2.3 High Strength and Durability

• Compression & Flexural Strength: Compression strength ranges from 20–40 MPa, and flexural strength from 10–20 MPa—suitable for load-bearing walls and subfloors.
• Long Lifespan: More than 20 years of service without degradation or chalking.
• Application Scenarios: Used in industrial buildings, exterior walls, and prefabricated structures.

2.4 Environmentally Friendly and Healthy

• Non-toxic: Free from formaldehyde, asbestos, and other harmful substances, compliant with GB 18580 E0-level indoor environmental standards.
• Recyclable: Low-pollution production and partially degradable, meeting green building requirements.
• Application Scenarios: Suitable for nurseries, eldercare facilities, and eco-conscious environments.

2.5 Good Insulation and Acoustic Properties

• Thermal Insulation: Thermal conductivity ranges from 0.07–0.12 W/(m·K), better than traditional concrete panels.
• Sound Insulation: A 12mm MGO board can block 30–40 dB of sound, suitable for partitions and ceilings.
• Application Scenarios: Ideal for meeting rooms, home theaters, or sound-sensitive residential areas.

2.6 Easy Installation

• Easy to Work With: Can be cut, drilled, and nailed—more workable than gypsum board.
• Lightweight: Density of 0.9–1.2 g/cm³, lighter than cement boards, easy to transport and install.
• Application Scenarios: Ideal for fast-paced construction, temporary structures, or renovation projects.

• Production Process of MGO Boards

The production process involves:

• • Raw Material Mixing: Proportional blending of MgO, MgCl₂, water, reinforcing fibers, and fillers to form a uniform slurry.
  • Molding: Pouring the slurry into molds with layered glass fiber mesh for structural reinforcement.
  • Curing: Cured at room or low temperatures (24–48 hours), with optional steam curing for faster setting.
  • Cutting & Surface Treatment: Once hardened, the boards are cut to size and optionally sanded, laminated, or coated.
  • Drying & Packaging: Final moisture removal, drying, and packaging before delivery.
