Purification Glass Magnesium Rock Wool Board
Overview
Purified Magnesium Oxide Rock Wool Board is a composite material made from magnesium oxide (MgO), rock wool, and reinforcing additives. It is engineered for high fire resistance (up to 4 hours of fireproofing), thermal insulation, and sound absorption. Widely used in commercial and industrial construction, it meets strict safety standards for partitions, cleanrooms, and HVAC system enclosures. The material is lightweight yet durable, simplifying installation while providing long-term performance.
Physical and Chemical Properties
The board exhibits a density of 1.2-1.5 g/cm³, ensuring structural stability without excessive weight. Its rock wool core provides Class A fire resistance (non-combustible) and thermal conductivity of 0.035-0.045 W/(m·K). The magnesium oxide surface resists moisture, mold, and corrosion, making it suitable for humid environments. Chemically inert, it does not emit harmful gases under high temperatures, complying with indoor air quality regulations.
Main Applications
Primary uses include fire-rated walls and ceilings in hospitals, data centers, and factories. Its soundproofing properties (up to 30 dB reduction) make it ideal for auditoriums and offices. In cleanrooms and laboratories, the smooth surface prevents dust accumulation and allows easy sterilization. Industrial applications include insulation for pipelines and equipment due to its thermal stability (up to 600°C).
Safety and Storage
While non-toxic, cutting or sanding the board generates dust requiring PPE (masks, goggles). Store flat on pallets in dry conditions to prevent warping. Dispose of scraps as non-hazardous waste. Avoid prolonged skin contact with raw edges to prevent minor irritation. Fireproof coatings may require additional ventilation during application.
B2B Procurement Guide
Specify thickness (commonly 15-100 mm) and fireproof ratings (e.g., ASTM E84 Class A). Request third-party test reports for verification. Bulk orders (containers or truckloads) reduce costs; lead times vary by customization. Partner with manufacturers offering CNC cutting for precise dimensions. Compare MOQs (typically 500-1,000 m²) and logistics options.
