Also referred to as MGSO4 board (Magnesium Sulfate Board), chloride free board or sulfate MGO board, magnesium sulfate board is a waterproof and lightweight non-flammable and non-asbestos panel product that is commonly used as decoration and construction. The board is made of magnesium oxide, magnesium sulfate, wood fiber and per-lite. Magnesium sulfate board has a specific temperature and a long curing duration. It provides excellent performance in stability, impact strength and bending strength.
Nowadays, it is widely used in building construction in recent years, its biggest advantage is not to absorb moisture back to halogen, and there are many sources of magnesium sulfate, including the reuse of industrial waste acid.The main raw materials of magnesium sulfate board are magnesium oxide, magnesium sulfate, perlite, halogen, fiberglass mesh and so on.
Mgso4 Boards(Magnesium Sulfate Board) are extremely suited for use in fire prone areas
