Class A Non-Combustible Fire Resistance of MGO Board

MGO board (Magnesium Oxide Board) uses magnesium oxide and magnesium chloride as cementitious materials, reinforced with glass fiber cloth, and forms a stable 5·1·8 crystal structure through chemical reactions. It boasts GB 8624-2012 Grade A non-combustible performance (equivalent to international standard EN 13501-1 Class A1). Its core fire-resistant advantages lie in: not burning or releasing toxic fumes when exposed to fire, maintaining structural integrity at high temperatures (≤1200℃), and effectively blocking the spread of fire. As a preferred material for building fire compartments, partition walls, suspended ceilings, and industrial fire protection scenarios, this fire-resistant performance is an intrinsic property of the material itself-it does not rely on additional fire-retardant coatings and its performance does not easily degrade with long-term use.
