Magnesium Oxide Board

A Magnesium Oxide Board (MgO Board) is a high-performance, eco-friendly building material made primarily from magnesium oxide (MgO), a naturally occurring mineral (often derived from magnesite or seawater), combined with reinforcing materials (such as fiberglass mesh) and binders. It is widely used in construction and interior/exterior finishing due to its exceptional properties.

Magnesium oxde board advantages

Non-combustible

Magnesium oxide board (MgO board) is a sustainable non-combustible material, suitable for both commercial and residential buildings. It can resist fire for 2-3 hours, does not burn at 800℃, and will only ignite when the temperature reaches 1200℃.

Water Resistant

MgO board has strong water resistance. It can maintain its structural integrity even with slight bending, and remains stable in humid environments, preventing warping, expansion or delamination.

Health and Safety

MgO board is mainly composed of magnesium oxide minerals. It does not contain fly ash, formaldehyde, crystalline silica and other toxins, making it a safe choice of building materials.

Termite-resistant

MgO board is naturally moisture-proof, fire-resistant, mold-proof and insect-proof. It can prevent deformation, expansion or decay, making it a durable choice of building materials.

ECO-Friendly

Our boards are made of natural compounds, which can be safely landfilled and recycled, and are regarded as ``nutritional waste``. Having passed 36 months of freeze-thaw cycle tests, they can be constructed all year round.

Mold-proof

Magboard has antibacterial properties, which can effectively prevent mold, fungi and decay. Using new technology has effectively solved the problems of slight corrosion and expansion.
