MGO sandwich panel

The MGO sandwich panel is made of magnesium sulphate board which is an inorganic raw material. Magnesium board is a fireproof and flame-retardant product composed of magnesium sulfate, magnesium oxide, glass fiber cloth and water. They have excellent physical and chemical properties. Light weight, high strength, fire-proof, non-toxic, tasteless, no radioactive pollution, fire-proof performance reaches GB8624a, high temperature resistance of 1200 degrees and non- combustion. Magnesium plate also has the properties of good toughness, no fracture, no separation from layers, high strength, sound insulation, heat insulation and no deformation. It is widely used in indoor decoration and the manufacture of various fire doors, fire-proof furniture and building partitions.


characteristics of MGO sandwich panel:


  • no Halogenation

Magnesium oxide and magnesium sulfate are used as the main materials to 100% eliminate the corrosion of color steel plate and aluminum alloy profile caused by chloride ion penetration caused by environmental impact. The scientific formula completely solves the problem of moisture absorption and halogen return of magnesite. The magnesium plate is durable, aging resistant and long service life.


  • Anti-shrinkage


The magnesium plate added with flame retardant polystyrene particles has the characteristics of anti-shrinkage, which can greatly alleviate the shrinkage problem of magnesium plate in low humidity and dry environment.


  • strong fire resistance


magnesium clean room sandwich panel has more fire resistance and can meet the national fire detection standard. It is the preferred purification product in the sandwich panel on the market at present.


  • Economic benefits

excellent processing and installation performance, superior toughness and not easy to fracture. Self-tapping screws, gun nails and straight nails can be used for lightweight installation.


  • Sound insulation

the superior sound insulation performance of magnesium plate ensures the quiet and elegant living environment. Its unique uniform pore structure is unmatched by other dense glass magnesium plates.


  • Insect and mildew prevention

inorganic mineral powder materials constitute the functions of glass magnesium plate against mildew, bacteria, insects and termites, which meet the anti-mildew standards of building materials in Europe and the United States.


Mgo sandwich panel is widely used, especially in the field of partition and ceiling materials in the field of architectural decoration. It is fully suitable for heat insulation structure, sound insulation wall, wet area, movable partition wall, special fire prevention, internal splint of fire door, external packaging of equipment box and other areas.

Mgo sandwich panel is a best choice for the clean room ceiling instead of polyurethane or rockwool, meanwhile, it can infill the rockwool inside the hollow magnesium panel for a better heat and sound insulation.
