Magnesium Oxide Fireproof Board
HAILING MgO fireproof board is a kind of environmental-friendly fireproof board, widely used in construction and decoration. Hailing company has several sets of automatic fireproof board production lines. And we use highly-purified active MgO as main fireproof material, high-quality magnesium chloride as the main cementing material to solidify other materials, alkali-resistance fiberglass mesh to ensure the high strength of board, soft sawdust and light non-combustible perlite as filling materials.
