Fireproof Wall Board

The fire-resistant property of MgO board is one of its core advantages, stemming from its unique material composition, structural characteristics, and related performance. The specific aspects are as follows:

1. Inorganic & Non-Flammable Material (Stops Fire at the Source)

Our magnesium oxide (MgO) board is made entirely from inorganic, fireproof raw materials - mainly magnesium oxide, magnesium chloride and magnesium sulfate. None of these natural mineral ingredients can catch fire.

We add a small amount of reinforcing materials during production, like plant fibers (straw, wood chips) or glass fibers. Even when exposed to high heat, these fibers get fully sealed inside the magnesium cement matrix. They carbonize instantly instead of burning or fuelling flames.

Unlike flammable organic boards such as wood or plastic, our MgO board is completely non-combustible by nature. It never feeds or spreads fire, which is the core reason for its outstanding fire resistance.

2. Zero Flame Spread & Ultra-Low Smoke Release

Tested in strict compliance with the ASTM E84 standard (also meets NFPA 701 and UL1975 requirements), our MgO board delivers top-tier fire performance:

In the full 10-minute ASTM E84 test, the board produces zero lateral flame spread. Thanks to its stable inorganic MgO-MgCl₂ structure, it resists ignition completely and achieves the highest Class A flame spread rating per ASTM E84-23b. Even under direct exposure to 1000℃+ open flames, only minor local surface heat damage occurs, with no continuous flame formation. It fully qualifies as a non-combustible building material per official building codes.

It also generates extremely little smoke during high-temperature decomposition. It scores a 0 smoke development index (SDI) with a smoke density rating below 15 - far better than the Class I maximum limit of 450 set by ASTM E84. This makes it a perfect low-smoke, low-toxicity material for high-standard public spaces like schools and hospitals.

3. Customizable Fire Resistance Rating by Thickness for All Scenarios

Fire resistance rating refers to how long the board can stay intact and heat-insulating in a fire. For MgO boards, this performance directly depends on thickness, covering all common application scenarios:

- 3–6mm thickness: 0.5–1 hour fire resistance rating. Ideal for interior decoration areas with basic fire safety requirements.

- 8–12mm thickness: 1–2 hour fire resistance rating. Perfect for conventional wall partitions, ceilings and regular fireproof zones.

- 15mm+ thickness: 2–4 hour fire resistance rating. With professional installation (sealed joints + keel fixation), it satisfies strict fire protection standards for high-risk areas, including fire compartments and equipment rooms.

4. Excellent Flame Penetration Resistance & Thermal Insulation

The board's dense, all-inorganic structure delivers great thermal insulation. In a fire, even when the surface is exposed to extreme high heat, the internal temperature rises very slowly. This effectively blocks heat transfer to the other side and prevents nearby materials from catching fire.

Besides, it boasts excellent high-temperature deformation resistance. It won't crack or break easily under intense heat, maintaining complete structural integrity for a long time to block flames and high-temperature gas penetration.

5. Full Compliance with Global Fire Safety Standards

Authentic third-party testing confirms our MgO board reaches the A1-class non-combustible grade (the highest fire safety level) per China's GB 8624-2012 standard. It fully meets fire protection design requirements for building walls, ceilings, partitions and other architectural applications.

Additionally, it complies with mainstream fire safety regulations for industrial scenarios, including industrial equipment protection and fire pipe wrapping. It effectively lowers overall fire risks for both construction and industrial projects.

Beyond Fire Resistance: MgO Boards Redefine Building Innovation
As a next-generation green building material, magnesium oxide (MgO) boards deliver six core advantages across their lifecycle:

1. Eco-Friendly & Healthy
Formulated without asbestos, formaldehyde, or harmful VOCs, MgO boards comply with ISO 14001 environmental standards and LEED certification requirements, ensuring superior indoor air quality.

2. Lightweight & Load-Optimized
With a density of 0.8–1.2 g/cm³, MgO boards reduce structural loads by 20–60% compared to traditional materials like concrete, gypsum, or fiber cement boards, enabling 5–8% increased usable space while enhancing seismic resilience..

3. Moisture & Thermal Resilience
Proven through ASTM D751/D752 testing, MgO boards maintain dimensional stability at 95% humidity, resisting swelling, warping, and mold growth due to their chemically inert MgO-MgCl₂ matrix.

4. Energy & Acoustic Efficiency
Combining low thermal conductivity (0.216W/cm·K, ASTM C518) with a Sound Reduction Index (Rw) ≥42dB (GBJ121-88), MgO boards achieve 1.14m²K/W thermal resistance and optimal noise control for energy-efficient buildings.

5. Design-Friendly Fabrication
Supporting on-site customization via cutting, drilling, or shaping, MgO boards seamlessly integrate with finishes like paint, tiles, or wood veneers, empowering architects to realize complex design visions.

6. Long-Term Durability
Our product demonstrates excellent compressive strength, withstands over 50 freeze-thaw cycles, and offers inherent pest resistance, ensuring maintenance-free long-term reliability under extreme environmental conditions.

From residential interiors to commercial complexes, MgO boards establish a new benchmark for sustainable architecture, merging safety, eco-performance, and functional innovation to build smarter urban futures.
