Magnesium Oxide Board Composition
Main Ingredients and Additives
You might wonder what makes a magnesium oxide board so strong and reliable. The answer lies in its special mix of ingredients. Each part plays a key role in giving the board its unique properties. Here is what you will find inside:
Magnesium Oxide (MgO): This is the main ingredient. It gives the board its fire resistance and strength.
Magnesium Chloride (MgCl2): This acts as a binder. It holds all the materials together and keeps the board solid.
Perlite: This lightweight mineral helps the board stay light and improves insulation.
Wood Fiber: This adds flexibility and extra strength.
Vermiculite: This mineral expands when heated, adding more safety.
Glass Mesh: This reinforces the board and makes it even tougher.
Phosphate: This helps create strong chemical bonds inside the board.
You can see that each ingredient has a special job. When you combine them, you get a board that is safe, strong, and ready for many uses.
Role of Glass Fiber, Perlite, and Wood Chips
You may ask why glass fiber, perlite, and wood chips matter so much. These materials do more than just fill space. They change how the board works and feels.
Glass fiber makes the board much stronger. Even a small amount can boost the board’s splitting tensile strength. For example, adding 0.6% glass fiber can increase strength by over 27%. You can see how the strength changes with more glass fiber in the chart below.

Perlite keeps the board light and helps with insulation. You get a board that is easy to handle and keeps rooms comfortable.
Wood chips or wood fiber add flexibility and extra toughness. The board can bend a little without breaking, which helps during installation.
Note: The right mix of these materials makes the magnesium oxide board a top choice for safe and modern buildings.
How Glass Magnesium Board Is Made
Raw Material Preparation
The first step is getting the raw materials ready. Workers pick good magnesium oxide and magnesium chloride. They also choose other important ingredients. Machines check if each material is pure and the same every time. This is important for making strong and safe boards. Workers also get glass fiber mesh, perlite, and wood chips ready. These things help the board fight fire and water. The factory keeps all the materials in clean, dry rooms. This keeps everything fresh and good to use.
Mixing and Forming Process
The next step is mixing and shaping the board. Special machines do most of the work. All the ingredients go into a big mixer. The mixer stirs them into a smooth liquid. This makes sure every board is the same. After mixing, workers pour the liquid into molds. The molds shape the boards and hold the glass fiber mesh. The mesh sits inside to make the board stronger. The molds get pressed to push out air and make the boards thick. Pressing helps the boards last longer and stay tough.
Here is a simple table that shows each step in the manufacturing process:
Step | Description |
|---|---|
Material Preparation | Select and prepare all raw materials. |
Mixing | Blend ingredients into a smooth slurry. |
Molding | Pour slurry into molds and add fiberglass mesh for strength. |
Pressing | Press molds to remove air and increase density. |
Curing | Let boards cure to harden and improve performance. |
After pressing, the boards need to cure. Curing makes the boards hard and strong. Quality checks happen at every step. Machines test the boards for fire, water, and strength. This careful work makes sure you get a safe board every time.
Modern Advancements in 2026
In 2026, factories use smart machines and new materials. Robots and sensors watch every part of the process. Automation helps make every board the same with no weak spots. New modifiers are added to the mix. These make the boards even safer and stronger.
Here is a table that shows how each component helps the board:
Component | Contribution to Non-Combustibility and Durability |
|---|---|
Magnesium Oxide | Gives fire resistance and keeps the board strong. |
Magnesium Sulfate | Adds moisture resistance and makes the board last longer. |
Fiberglass Mesh | Makes the board tougher and safer in a fire. |
Lightweight Aggregates | Keeps the board light but strong. |
These new changes help the boards fight fire and water better. Fiberglass mesh makes the boards stronger. Lightweight aggregates make the boards easy to carry. The special mix stops bad gases from forming in a fire. This keeps people safe in buildings.
Tip: Modern factories use strict quality checks. Every glass magnesium board must pass tests for fire, water, and strength before it leaves the factory.
You can trust the 2026 process to make safe and strong boards. These boards are ready for any building job.
MGO Board Properties and Benefits
Fire and Moisture Resistance
You want your building to be safe. An mgo board protects against fire. It can stand flames for four hours. This is good for fire walls and barriers. The board also stops water from soaking in. It keeps its shape and stays strong in wet places. In humid areas, builders saw no mold on mgo boards. After one year, rooms with these boards had less humidity and no mold. You can trust mgo board to keep your space safe from fire and water.
Here is a table that shows how mgo board compares to gypsum boards:
Material | Fire Resistance Duration | Moisture Resistance | Mold Resistance | Non-combustibility |
