Key Fire Performance Points of MGO Board
Apr 14, 2026
- MGO board (Magnesium Oxide Board) is a non-combustible fireproof building material, usually reaching Class A non-combustible standard.
- Its main raw material is magnesium oxide, with excellent fire resistance and flame retardancy, and does not support combustion or release toxic smoke in case of fire.
- It has a high fire resistance limit, can maintain structural stability under high temperature, and effectively block flame spread.
- It performs well in high temperature resistance, does not melt, drip or crack easily under fire, and provides effective fire protection time.
- Environmentally friendly and safe: no harmful gases such as halogen and formaldehyde are released during combustion, which meets fire safety and environmental protection requirements.
- Widely used in fire partition walls, ceiling systems, cable troughs and other parts with high fire protection requirements.
