Rubri Magnesium sulfate board is also called Chloride Free MGO Board or Magnesium Sulfate Mgo Board. It is an upgraded product for mgo board, fiber cement board and calcium silicate board. Rubri Magnesium sulfate board, as a new type of non-flammable building material, is a environmental-friendly board widely used in construction and decoration. Rubri Magnesium sulfate board is made of magnesium oxide, magnesium sulfate, wood fiber, agricultural waste, glass fiber and others.
