What is Magnesium Oxide Sulfate Board?

Magnesium Oxide Sulfate Board, also known as chloride-free magnesium oxide board or chloride-free mgo board, is a type of construction material primarily made from magnesium sulfate (MgSO4). This material is created by combining magnesium powder with sulfuric acid to form magnesium sulfate, which is then compressed and heated to produce a dense, strong, and fire-retardant board.

Advantages of Magnesium Oxide Sulfate Board:

1. Chloride-free: Unlike traditional magnesium oxide boards, magnesium oxide sulfate boards are made primarily from magnesium sulfate, not containing chlorides. This makes them suitable for use in environments where the corrosion of metal components is a concern.
2. Fire Resistance: The board is non-flammable and has a fire rating of A1. It can withstand high temperatures, melting, or burning without losing its structural integrity.
3. Thermal Insulation: It has good thermal insulation properties and is widely used in fireproof and thermal insulation applications for walls.
4. Moisture Resistance: Magnesium Oxide Sulfate Board exhibits excellent moisture resistance and does not crystallize after absorbing moisture, which is beneficial for various construction purposes.
5. Durability: It has high compressive strength, durability, and requires minimal maintenance, making it long-lasting.
6. Environmental Impact: It is environmentally friendly and does not release toxic chemicals, contributing to a greener construction industry.

What Are Magnesium Oxide Sulfate Board Used for ?

Fireproofing: With a fire rating of A1, magnesium oxide sulfate boards are commonly used to protect structural elements from fire, reducing the risk of structural collapse during a fire.

Subflooring: Due to their durability and moisture resistance, magnesium oxide sulfate boards can be used as subflooring materials, helping to create a stable and long-lasting floor structure.

Exterior and Interior Walls: Their ability to withstand high temperatures and resist fire makes them suitable for use in both exterior and interior wall systems.

Roofing: Magnesium oxide sulfate boards can also be used in roofing applications, providing fire protection and thermal insulation.

Decorative Elements: The smooth surface of magnesium oxide sulfate boards can be used for decorative purposes, such as wainscoting or paneling, thanks to their aesthetic appeal and fire-resistant properties.
