MGO, an inorganic mineral material, has become the preferred core material for high-performance cleanroom panels. Its exceptional physical and chemical properties perfectly meet the stringent requirements of controlled environments for safety, stability, and hygiene.
I. Core Advantages of MGO
- Exceptional Fire Performance (Core Safety)
- Advantage: MGO itself is a Class A1 non-combustible material. It does not burn when exposed to fire, effectively blocking the spread of flames and providing critical time for evacuation and emergency response.
- Relevant Data: Complies with ASTM E84 standards, typically achieving a Flame Spread Index of 0 and a very low Smoke Developed Index. Fire resistance rating can reach up to 4 hours or more.
- Excellent Moisture and Mold Resistance (Ensures Cleanliness)
- Advantage: MGO’s very low water absorption rate ensures stability even in high-temperature and high-humidity environments, fundamentally preventing mold and bacterial growth, thereby guaranteeing the sterile conditions of the cleanroom.
- Relevant Data: 24-hour water absorption rate is typically < 5%, significantly lower than traditional gypsum board (>30%) or other organic materials.
- High Strength and Superior Durability (Structural Stability)
- Advantage: MGO panels exhibit high compressive and flexural strength, resisting deformation, cracking, or sagging, ensuring long-term flatness and integrity of the cleanroom enclosure.
- Relevant Data:
- Flexural Strength: Typically ≥ 15 MPa
- Compressive Strength: Typically ≥ 1.5 MPa
- Environmental Friendliness and Health (Meets High Standards)
- Advantage: MGO material is non-toxic, odorless, and has virtually zero formaldehyde emissions (NAF grade), providing a healthy indoor environment for industries with strict VOC control requirements such as healthcare, food, and electronics.
- Relevant Data: Formaldehyde emissions comply with CARB NAF (No Added Formaldehyde) and LEED green building standards.
- Outstanding Dimensional Stability (Long-Term Maintenance)
- Advantage: The panels exhibit extremely low rates of expansion and contraction under varying temperature and humidity conditions, avoiding seam cracking caused by deformation and reducing maintenance costs.
II. Summary Comparison Table
| Property | MGO Core Cleanroom Panels | Traditional Gypsum Board/Calcium Silicate Board |
|---|---|---|
| Fire Rating | Class A Non-Combustible | Class B1 Flame Retardant or Class A |
| Moisture/Mold Resistance | Excellent, Water Absorption <5% | Poor, Prone to Moisture Damage and Mold |
| Strength & Durability | High, Resists Deformation | Lower, Susceptible to Damage |
| Eco-friendliness & Health | Excellent, Formaldehyde-Free, Non-Toxic | May contain harmful substances; careful selection needed |
Conclusion:
For critical environments such as cleanrooms, laboratories, and hospital operating rooms, choosing cleanroom panels with an MGO core means selecting the highest safety, long-term stability, and reliable cleanliness assurance.
