Product Description
Chloride Mgo Board / Magnesium Oxide Board
Magnesium Oxide (MgO) Boards, also known as MgO Boards, are a modern building material known for their superior properties. These boards are primarily composed of magnesium oxide, a compound that is both non-flammable and non-toxic. They are known for their resistance to fire, water, and mildew, making them ideal for a variety of building applications. MgO Boards are also known for their strength and durability, providing a strong solution for both indoor and outdoor use. They are environmentally friendly, made from natural materials, and are often used as an alternative to traditional drywall, especially in areas where moisture and fire safety are concerns. MgO Boards can be used in interior walls, ceilings, subflooring, and as part of fireproofing assemblies, demonstrating their versatility in the construction industry.
What is difference between Mgo board and Mgso4 board?
Composition: MgO boards are made primarily from magnesium oxide (MgO) and are often reinforced with a glass fiber mesh. The key binding agent in these boards is magnesium chloride (MgCl₂).On the other hand, MgSO₄ boards use magnesium sulfate (MgSO₄) as the binder instead of magnesium chloride.
Moisture Absorption: MgO boards, due to the presence of magnesium chloride, are more prone to moisture absorption. This can lead to issues such as "weeping," where moisture seeps from the board, potentially causing corrosion of metal fasteners and framing.In contrast, MgSO₄ boards are much less hygroscopic (attractive to water) than MgO boards with magnesium chloride. This makes MgSO₄ boards more resistant to moisture absorption, effectively blocking the halogen-related issues and significantly enhancing the water resistance of the board.
Corrosion Resistance: MgSO₄ boards, being free of chloride ions, prevent corrosion of metal fasteners and frames, making them non-corrosive and an improvement over earlier MgO boards that posed a risk to steel framing or metal components.
Applications: MgSO₄ boards, because of their improved moisture resistance and stable composition, are better suited for coastal regions, high-humidity environments, or applications where long-term durability is essential.

1.What is OCM® mgo board made of? What is the chloride content?
The main component of OCM® Mgo board is MgO which is completely non-flammable and can be used for fire protection.
There are mainly two different types of salt:
- Magnesium oxychloride hydrated /Mgcl2 (steel corrosion risk)
-Magnesium oxysulfate hydrate/Mgso4(OCM mgo board)
OCM® MgO Board is a chloride-free Mgoso4 board. It uses magnesium sulfate instead of magnesium chloride.magnesium sulfate makes MgSo4 panels incredibly waterproof by preventing moisture from absorbing back into the halogens in the board.
According to The China Magnesium Oxide Board Industry Association issued a new standard of magnesia board industry, dissolvable (free) chloride ion content is below 5%, Content of Chloride is below 10%.
OCM mgso4 board Chloride content is below 0.012%, with reference to ASTM C871-11
you don't have to worry about "crying boards" when you use OCM® MgO Board on steel or metal frame.
