When it comes to construction, safety isn't just a box to check—it's the foundation of a secure home. Magnesium sulfate wallboard with Jinpeng Group -- MagMatrix brand BMSC 517 new sulfate formulation and technology has emerged as a top-tier material for builders and homeowners who refuse to compromise on safety. Its unique inorganic composition offers superior defense against two of a building's biggest threats: fire and water.
Here is why MagMatrix brand BMSC 517 new magnesium sulfate wallboard is the smart investment for modern construction.
Unmatched Fire Resistance Magnesium Sulfate Wallboard
In the event of a fire, every second counts. Magmatrix brand BMSC 517 new Magnesium sulfate wallboard offers significantly more protection than traditional materials, giving occupants crucial time to evacuate.
Withstanding Extreme Heat for Magnesium Sulfate Wallboard
The difference in heat tolerance is staggering. Standard gypsum drywall begins to degrade around 150°C. In contrast, the magnesium oxide found in these boards has a melting point of approximately 2,800°C.
This high melting point allows the board to maintain its structural integrity for up to 4 hours during a fire, whereas standard drywall often fails in less than one hour.
The Science of "Bound Water"
One of the board’s most clever features is its internal inorganic formulation. It contains hydration reaction bound crystalized water. When exposed to fire, this water converts into steam. This reaction absorbs heat and actively slows the spread of flames, acting as a built-in fire suppression system.
Superior Moisture and Mold Control
Water damage is a homeowner’s nightmare, often leading to structural issues and health hazards. MagMatrix's Magnesium sulfate wallboard is engineered to thrive where other materials rot.
A Healthier Home Environment
Mold requires organic material (food) and moisture to grow. Because magnesium sulfate boards are completely inorganic, they provide zero food source for mold spores. This creates a naturally antifungal environment, ensuring cleaner indoor air quality for your family.
Built for Humidity
While gypsum boards act like sponges—absorbing up to 3% of their weight in moisture and swelling as a result—MagMatrix's magnesium sulfate boards are incredibly stable.
Absorption Rate: They absorb as little as 0.34% of moisture.
Long-Term Durability: In testing, these boards withstood over 800 days in 90% humidity at 30°C without swelling, warping, or degrading.
This makes them the ideal choice for high-moisture areas like bathrooms, kitchens, and basements and for the fire rated structural wall, subfloor and roofing sheathing panels.
Comparison: Magnesium Sulfate vs. Gypsum Drywall
To see why builders are making the switch, look at the direct comparison:
Feature | Magnesium Sulfate Wallboard | Standard Gypsum Drywall |
Fire Rating | ASTM E136 / Class A (Non-combustible) | Combustible (low heat tolerance) |
Heat Limit | Up to 2,800°C | Approx. 150°C |
Water Reaction | Retains shape; no swelling | Swells and deforms |
Mold Resistance | High (Inorganic) | Low (Organic paper facing feeds mold) |
Benefits for Builders and Homeowners
Choosing MagMatrix's magnesium sulfate wallboard isn't just about technical specs; it’s about practical benefits on the job site and in the home.
Eco-Friendly: These boards are recyclable and have a lower carbon footprint than many traditional materials.
Easy Installation: Builders appreciate that it installs similarly to drywall but offers a cleaner cut and creates less dust.
Peace of Mind: For homeowners, the knowledge that their walls are fire-resistant and mold-proof offers invaluable security.
Frequently Asked Questions
What makes this wallboard fireproof? It is made from magnesium oxide, a mineral with an incredibly high melting point. It does not burn, produce toxic smoke, or fuel a fire.
Can I use it in my shower or basement? Absolutely. It is highly moisture-resistant and will not warp or swell, making it ideal for damp environments.
Will it prevent mold? Yes. Since the board contains no organic material, mold has nothing to eat, preventing growth even in humid conditions.
Is it difficult to install? No. It can be cut and fastened much like standard drywall, though it is stronger and more durable.
