Class A1 Fire Resistance
The Magnesium Oxide core provides superior non-combustible properties, enduring high temperatures exceeding 1200°C without releasing toxic fumes.
-

Moisture & Mold Proof
Unlike gypsum or standard rockwool, MgO composition is naturally resistant to water absorption, preventing bacterial growth and mold proliferation essential for GMP standards.
-

Chemical Resistance
The pre-painted galvanized steel (PPGI) surface withstands rigorous cleaning protocols involving VHP (Vaporized Hydrogen Peroxide) and alcohol-based sanitizers.
-

High Flexural Strength
Impact-resistant construction suitable for high-traffic cleanroom corridors. The modular tongue-and-groove system ensures airtight seals.
The Magnesium Oxide Cleanroom Panel is the industry standard for facilities requiring stringent fire safety codes combined with sterile surface requirements.

FAQ
Q: What is a MgO cleanroom panel?
A: The MgO cleanroom panel is a new type of fireproof and environmentally friendly composite board. It typically uses a magnesium oxide board (made of magnesium oxide, magnesium chloride, fiberglass cloth, etc.) as the face or inner lining, filled with rock wool, polyurethane, or employing a hollow structure.
Common types: Solid magnesium oxide rock wool cleanroom board (fireproof and heat-insulating), hollow magnesium oxide cleanroom board (lightweight, high strength).
Q: How to choose between hollow and solid magnesium oxide rock wool boards?
Hollow magnesium oxide board: The interior has a mesh structure, making it relatively lightweight and extremely hard. Suitable for return air walls or partitions requiring pipework.
Solid magnesium oxide rock wool board: The entire core is filled with rock wool, providing better thermal insulation and soundproofing. Suitable for partitions or ceilings requiring thermal and sound insulation.

Q: What should be noted during installation?
A: Sealing and waterproofing: Since it's a cleanroom, the joints between boards must be tight, and the sealant must be applied evenly to prevent moisture from entering the interior.
Corrosion Protection: Since magnesium oxide materials themselves have a certain degree of alkalinity or salinity, it is recommended that the aluminum profiles in contact with them undergo anti-oxidation treatment, and nail holes should be sealed properly.
Weight Considerations: Magnesium oxide boards are relatively heavy; the density and strength of the suspension rods must be carefully calculated during ceiling construction.
