OCM Lightweight EPS Interior Partition Fireproof Magnesium Oxide Board

Lightweight Mgso4 Cement Board
        Lightweight MgSO4 Cement Board is an innovative, eco-friendly construction material known for its exceptional fire resistance and moisture control. Composed of magnesium oxide, magnesium sulfate, wood fiber, and perlite, this board is designed to be lightweight yet remarkably strong, offering superior stability, impact strength, and bending strength . It is non-flammable, non-asbestos, and provides thermal and acoustic insulation, making it ideal for use in Structural Insulated Panels (SIPs), decorative applications, and as a sub-roof board or underlay for floor and wall tiles . With its waterproof properties and chloride-free composition, it prevents moisture from being reabsorbed, avoiding the 'sweating' and metal corrosion issues associated with some other boards . This makes the Lightweight MgSO4 Cement Board a reliable choice for both interior and exterior applications where durability and safety are paramount.

Lightweight MgSO4 Cement Board, also known as magnesium sulfate board, offers several advantages over traditional building materials:

  1. Fire Resistance: MgSO4 boards display superior fire performance, being non-flammable and providing excellent insulation against heat and smoke, which is a significant upgrade from traditional materials that may not offer the same level of protection.

  2. Moisture and Mold Resistance: These boards are fully waterproof, preventing swelling, warping, or mold formation, even in high-humidity environments, which is a notable improvement over materials that can degrade in wet conditions.

  3. Thermal and Acoustic Insulation: MgSO4 boards provide excellent insulating properties, making them ideal for improving energy efficiency and soundproofing in buildings, a feature that may not be as pronounced in traditional construction materials.

  4. Lightweight and Easy to Work With: Their lightweight nature simplifies transportation, cutting, and installation, reducing labor intensity compared to heavier traditional materials.

  5. Eco-Friendly Manufacturing: MgSO4 boards are produced with relatively low carbon emissions, aligning with sustainable construction practices, whereas traditional materials may have a higher environmental impact due to their production processes .

  6. Longevity: These boards are structurally strong and do not break, bend, or deteriorate over time. They maintain their integrity even under demanding conditions, offering a longer lifespan than some traditional building materials.

  7. Resistance to Pests and Fungi: MgSO4 boards are naturally resistant to termites and mold, a beneficial property over materials that may require additional treatments to prevent infestation.

  8. Health and Safety: Free from harmful chemicals like formaldehyde, asbestos, and silica, making it safer for indoor use compared to materials that may off-gas or contain harmful components.
