Product Introduction
Building Materials MGO High Strength Low Density Fireproof Magnesium Oxide Board
MGO board, or magnesium oxide board, is a new kind of non-flammable composite board. It's made with three main things: high-purity active magnesium oxide, either magnesium chloride or magnesium sulfate, and water. We add some special additives to improve it, reinforce it with alkali-resistant fiberglass mesh, and fill it with light materials like perlite, then make it through special processes.
It has the light weight and flexibility of wood-based boards, plus the fire and water resistance of inorganic boards. It's a great eco-friendly building material that's perfect for replacing the old gypsum boards and plywood.
Advantages of Building Materials MGO High Strength Low Density Fireproof Magnesium Oxide Board
1 Lightweight But Super Strong (Our Best Advantage)
It's really light, way lighter than traditional building materials, so it reduces the building's load a lot.But it's also super strong-stronger than other similar lightweight panels.It's got great strength for its weight, much better than gypsum boards and cement boards, so it's light but tough.
2 Great Fire ResistanceIt's non-combustible (Grade A1)-
it won't burn or help fires spread, acting as a safety barrier.It stays structurally intact even at high temperatures, slowing down fire spread and giving more time to evacuate.Perfect for high-rises, hospitals, malls, and important places like machine rooms and power distribution rooms.
3 Excellent Water & Moisture Resistance
It doesn't absorb much water and handles moisture really well, great for damp spots like basements, bathrooms, and kitchens.It won't deform or swell even if soaked for a long time, and stays stable through wet and dry cycles.It also doesn't have the efflorescence problem that old magnesium panels usually have.
4 Eco-Friendly & Healthy
No harmful stuff like asbestos, formaldehyde, or benzene-totally non-toxic.It uses less energy to make than cement, cutting down on carbon emissions.It absorbs CO₂ while curing, helping with carbon neutrality, and it's 100% recyclable, which fits circular economy ideas.
5 Other Advantages
Weather Resistant: It resists acid, alkali, insects, and termites. It lasts 25-50 years, so you save on maintenance costs.Easy to Process: You can saw it, nail it, and glue it easily-speeds up construction and saves a lot of working time.
6 Good Nail Holding Power:
Better than gypsum boards, so decoration surfaces stay firm and safe.Smooth Surface: You can paint it, tile it, or paste things on it directly-no need to level it first.Mold Resistant: It's an inorganic material, so it doesn't grow mold. Perfect for hospitals, food workshops, and other places that need high hygiene standards.
