Magnesium Oxide Board

 

What is magnesium sulfate board？

BULU magnesium sulfate oxide board is a MgO board with embedded high-strength glass fiber mesh, which can achieve the comprehensive excellent mechanical properties of fire wall board. The most important difference is that it does not contain chloride ions and can effectively prevent halogen in humid areas and rainy weather. At the same time, it meets the ASTM E84 non-combustible standard, has little impact on the environment, and provides a very stable substrate for the construction industry with fire protection requirements. It can be combined with a variety of surface treatments. SGS test reports can be provided to customers and the market, and our BULU magnesium sulfate board has passed various tests in the UK and the United States.

MgO board is often seen as an alternative to traditional materials such as concrete, gypsum and drywall. What makes BULU fire wall board different is that it can outperform these materials in several key areas, including fire resistance, durability and resistance to various environmental factors.

BULU magnesium sulfate oxide board is a more environmentally friendly material than other traditional building materials. The production process of magnesium oxide is energy-saving and produces very little greenhouse gas, which is a potential factor in the increasing popularity of this material.

In summary, magnesium sulfate board is a high-performance, environmentally friendly modern building solution that provides fire protection, moisture resistance, durability and insulation benefits for a variety of applications.

Magnesium Oxide Fireproof Partition Board Production Process

Our BULU MgO fireproof board is made from high-end magnesium oxide powder, containing more than 70% inorganic matter and alkali-resistant high-strength fiberglass mesh. It is inorganic and has no toxic components. It does not contain formaldehyde or crystalline silica - ingredients commonly found in plywood, OSB, fiber cement and gypsum-based building materials. It achieves its superior strength and flexibility through the input of alkali-resistant high-strength fiberglass mesh, which gives our boards unique high-performance structural properties. Our boards use a low-energy manufacturing process that uses 50% less energy than competing building products and actually absorbs CO2 from the atmosphere during the exothermic curing process.

Magnesium Oxide Board Advantages

Snap Cut and Handle Easily

BULU MGO Fireproof Board is easy to install, cut, drill, shape and fasten. It can be machined like wood and drywall, making it easy to score, snap and maintain. The boards are compatible with carbide tools, which produce clean, square cuts for a quality installation. Disposable cutters can also be used for scoring and snapping, which can cleanly cut fiberglass mesh. When using a saw with precise depth adjustment, such as a manual power saw, the boards can be cut directly from the pile without leaving marks on the underlying boards. Construction crews typically use pneumatic roofing nail guns to fasten wallboard, and screws, framing nails and siding nails can also be used. Cutting BULU MGO Board is easier than cutting fiber cement because it produces less dust. The boards will not break during installation or when the edges are fastened with screws.

Highlight: Not Sweating

Since 2010 Denmark has witnessed a great loss of over EUR100 million caused by unqualified MgO “sweating board”. Different from those, BULU MgO boards are halogenide resistant and will not sweat because of the soaking process, as shown in the video.

Our BULU MGO board is durable and breathable. Our board resists moisture extremely well. It has a natural ability to absorb and wick away moisture, making buildings heavier and more durable. It can replace oriented strand board (OSB), plywood, and gypsum board for all sheathing, siding, subflooring, and roofing applications.

Formaldehyde Free, Non-Toxic ENF

BULU MGO Fireproof Building Boards are free from harmful chemicals, gypsum, cement-based materials, and formaldehyde. Made from 100% sustainable and compostable materials, these boards are CO2 negative and breathable, contributing to a healthier indoor environment. Unlike many conventional building materials, BULU MGO Boards do not emit gases, making them ideal for individuals sensitive to chemicals. These boards comply with ENF standards, ensuring they meet stringent environmental and safety requirements. Their non-toxic nature makes them a safe choice for both residential and commercial applications, providing a safe, eco-friendly solution without compromising on performance.

High Bending strength and screw pull-out force

BULU MGO Board is reinforced with 4 to 6 layers of high-tensile fiberglass mesh, providing exceptional bending strength of over 22 MPa and impact strength exceeding 38 MPa. This unique construction ensures superior tensile strength, making the board highly durable for various applications. The use of fiberglass mesh enhances the board's resistance to damage, offering a more robust and long-lasting alternative to traditional drywall.

 

Unlike conventional drywall, which is prone to surface wear, abrasions, and dents that require frequent cosmetic repairs, BULU MGO Board offers increased resistance to these issues. Its durability helps maintain a pristine appearance over time, reducing the need for ongoing maintenance and repair. The high impact and bending strengths make it an ideal choice for areas exposed to higher levels of wear and tear, such as commercial spaces, public buildings, and high-traffic areas.

Excellent acoustic and thermal insulation properties

BULU MGO Board can be combined with modern insulating materials (such as insulation boards and building membranes) for use in exterior building finishes. The board’s low thermal conductivity (0.0186 W/mK) and sound transmission value (30 dB) make it an effective barrier against both heat and noise. These characteristics help improve energy efficiency by reducing heat transfer and enhancing soundproofing, making BULU MGO Board an ideal choice for environments that require noise control and temperature regulation. Its superior performance in both insulation and soundproofing contributes to a more comfortable and energy-efficient indoor environment.

Excellent Dimensional Stability

BULU MGO Board exhibits minimal expansion in both high temperature and extreme humidity environments, ensuring that its structure remains intact under a wide range of conditions. The board has excellent impact resistance, making it suitable for most industrial applications, even in challenging environments. BULU MGO Board is a sponge-like porous material that does not completely absorb water into its pores, leaving it with room to expand when frozen. This prevents any structural changes during freeze-thaw cycles. As a result, the board maintains its integrity and performance in cold conditions, ensuring long-term durability.

BULU MGO Board has an impressive dimensional stability, withstanding up to 50 freeze-thaw cycles with a loss in mechanical strength of only 0.5%, well below the permissible limit of 18%. This makes it a reliable material for applications where temperature fluctuations and high humidity are common, maintaining its structural and mechanical properties over a long period of time.
