Product Introduction
Quick Drying Fireproof Magnesium Oxide Sulfate MGO Panel Floor Board
This quick-drying, fireproof magnesium oxide sulfate (MGO) floor panel - also called MgSO₄ floor board or sulfate magnesium oxide subfloor panel - is a new, chloride-free building material made just for flooring.It's an improved version of traditional MGO boards. Instead of magnesium chloride (MgCl₂), we use magnesium sulfate (MgSO₄), making it more stable, durable, and corrosion-resistant.The "quick-drying" part means it uses a special production process that speeds up curing time without losing strength. That's why it's perfect for fast-track construction projects.
Advantages of MGO Board
Fire Protection
- A1 Class Non-Combustible Rating: Highest fire safety classification, does not burn even at 800°C+ temperatures
- 3+ Hours Fire Resistance: Releases crystalline water during combustion to absorb heat and prevent flame spread
- No Toxic Emissions: No harmful gases released when exposed to fire, ensuring occupant safety
Moisture & Corrosion Resistance
- Chloride-Free Formula: Eliminates "sweating" issues and prevents corrosion of steel structures, making it ideal for steel-framed buildings
- Water Stability: Resists deformation even after 72+ hours of water immersion
- Low Water Absorption: Typically 12-18% (vs. 30%+ for calcium silicate boards)
- Mold & Mildew Resistant: Inorganic composition prevents microbial growth in high-humidity environments
Quick Drying & Installation Benefits
- Rapid Curing: 24-48 hours curing time (vs. 72+ hours for standard MGO boards)
- Immediate Traffic Readiness: Can be walked on and finished within days of installation
- Lightweight: 800-1250 kg/m³ density (lighter than cement boards), reducing transportation and installation costs
- Easy Workability: Can be cut, drilled, and shaped with standard tools; tongue-and-groove design ensures seamless installation
Structural Performance
- High Flexural Strength: 15-22 MPa (superior to plywood and OSB)
- Excellent Load-Bearing Capacity: Withstands heavy loads (suitable for commercial high-traffic areas)
- Dimensional Stability: Low expansion/contraction rate (<0.1%), maintains shape in extreme temperature/moisture changes
- Impact Resistance: Resists cracking from dropped objects, ideal for industrial and residential applications
Environmental & Health Benefits
- Non-Toxic & Eco-Friendly: No asbestos, formaldehyde, PVC, or heavy metals
- Low VOC Emissions: Exceeds ENF formaldehyde standards, improving indoor air quality
- Sustainable Production: Utilizes abundant mineral resources, recyclable at end of life
Workability & Installation
- Lightweight (20-30% lighter than cement board of same thickness) for easier handling
- Easy to cut, shape, and install (scoring and snapping like drywall, or using standard woodworking tools)
- Strong fastener retention (allows direct cladding attachment without needing to reach structural framing)
Quick Drying Fireproof Magnesium Oxide Sulfate MGO Panel Floor Board
High-purity Magnesium Oxide (MgO): Primary binder, provides fire resistance and structural strength
Food-grade Magnesium Sulfate (MgSO4): Activator, replaces MgCl2 to eliminate corrosion issues and improve water resistance
Reinforcing Material: Glass fiber mesh (4-6 layers for enhanced tensile strength)- Non-woven fabrics (improves flexibility and impact resistance)
Fillers: Wood chips/perlite (reduces weight while maintaining strength)- Mineral additives (enhances dimensional stability and quick drying properties)
Special Additives: Water repellents, setting accelerators, and anti-cracking agents (for quick drying and long-term durability)

Installation Guidelines
- Substrate Preparation: Ensure level, clean, and dry surface; fix any unevenness
- Panel Layout: Start from the corner, leave 2-3mm expansion gaps at walls and joints
- Fixing Method: Use corrosion-resistant screws (stainless steel or galvanized) spaced 200-300mm apart
- Joint Treatment: For T&G panels, ensure tight fit; for square edge panels, use special joint tape
- Finishing: Can be directly covered with flooring materials after 24 hours of installation (due to quick drying)
