MGO Tile Backer Board
As a backer board, MGO board boasts exceptional moisture resistance. It maintains structural integrity in humid environments, features a low water absorption rate, prevents expansion and mold growth, and unlike gypsum board or OSB, it does not soften or rot even after long-term exposure to water.
- Fast Delievery
- Quality Assurance
- 24/7 Customer Service
Product Introduction
The characteristics of magensium oxide board(MGO board) used as a backer board:
1. Exceptional Fire Safety Performance
- Class A1 Non-combustible: Does not combust at 800°C; produces no open flame at 1200°C. Fire resistance rating exceeds 3 hours. Absorbs heat when exposed to fire, delaying temperature rise in enclosed spaces and providing critical evacuation time.
- Fire Retardant & Smoke Suppression: Inorganic composition releases no toxic fumes when exposed to fire, meeting stringent safety requirements for high-risk environments (e.g., hospitals, labs).
2. Superior Moisture & Water Resistance
- Waterproof & Anti-mold: Maintains structural integrity after water immersion; naturally dries without deformation or softening. prevents swelling or mold growth in humid environments (e.g., bathrooms, basements).
- Corrosion & Pest Resistant: Inorganic raw materials resist acid/alkali corrosion and contain no organic matter or a little, eliminating risk of insect or rodent damage.
3. Lightweight & High-Strength Structural Advantages
- Low Density, High Strength: This material's low density (0.8~1.0g/cm³, >60% lighter than concrete) drastically reduces dead load, while its high impact and flexural strength ensure exceptional durability and damage resistance.
- Dimensionally Stable: Low thermal expansion and moisture deformation rates minimize warping or cracking over time.
4. Eco-Friendly & Health Benefits
- Zero Pollution Emissions: Composed of natural minerals (magnesium oxide) and plant fibers. Contains no formaldehyde, asbestos, benzene, or other VOCs. Safe for immediate occupancy after installation.
- Inherently Antibacterial: Factory-treated surfaces achieve >99% antibacterial rates, ideal for sterile environments (e.g., labs, cleanrooms).
5. Workability & Finish Compatibility
- Easy Fabrication: Can be cut (utility knife/composite saw), drilled, nailed, or glued with standard tools. Smooth surface readily accepts paints, tiles, laminates, wallpapers, or bonded finishes (stainless steel/PVC).
- Lightweight Installation: Significantly lighter than traditional cement fiberboard, this material reduces labor costs, handling effort, and installation complexity.
6. Durability & Cost Efficiency
- Long Service Life: Delivers decades of reliable performance, with premium grades achieving structural-life durability. Moisture and chemical resistance ensure low maintenance throughout service.
- Versatile Replacement: Replaces traditional materials (plywood, cement board, etc.) with thinner profiles while maintaining strength, reducing both material usage and installation space requirements.
Key Applications
- Residential: Cabinet backsplashes, bathroom wall lining, furniture substrates.
- Commercial: Hospital partition backing, laboratory moisture barriers, fire-rated dividers (malls).

MGO Tile Backer Board Application Scenarios:
Magnesium oxide board can be used indoors because it is resistant to fire, mold, insects, water and termites. These boards can be scored, broken, sawn, drilled and fixed to the wood or steel frame, which is convenient for installation.

MGO Tile Backer Board Product Features:
- Water Resistant Performance
Maintains strength after 25-day water immersion; naturally dries without deformation.
- Mold & Bacteria Resistance
Inorganic composition eliminates organic food sources for mold.
- Dimensional Stability
Minimal expansion/contraction (<0.3%) in high humidity (RH 95%).
Ideal for: Wet-area walls (bathrooms/kitchens), basement linings, and tile underlayments where moisture intrusion is a concern.
About Us
As the Chair of the International Exchange Committee at the China Magnesium Materials Association (CMMA), we work closely with the Magnesium Oxide Building Materials Association (MgOBPA) and the Magnesium Oxide Association (MOCA) to promote MGO board as a high-performance building material.
We are actively involved in developing industry standards, including the ASTM standards, to support the standardization and global growth of MGO products.
