Magnesium plate glass (commonly known as magnesium oxide board) is magnesium oxide,
magnesium chloride, and water ternary system, configured and made modifiers and processing,
stable performance magnesia cementitious material to neutralize alkaline fiberglass mesh to
enhance the materials to lightweight materials for filler composite made of new non-combustible
decorative materials. Processed using a special production process, with a fireproof, waterproof,
odorless, non-toxic, ice-free, does not rot, does not crack, the same, non-flammable, high strength
and light weight, easy construction, long service life and etc.
