Product Description

 

Its most important ingredient is MGO (Oxygen, when combined with magnesium under heat and pressure can produce a stone-like material: MgO). About 70% of the world's MgO is in Asia and China shares the largest part of MGO deposits. This is why thousands of years ago Chinese people already used MGO in Great Wall construction. Other famous examples are: 2008 World Olympics construction in Beijing, the world famous Taipei 101 building and middle east pyramids etc.  MGO production industry in China has always been very strong. Except for Mgo, Mgo board composition also includes: MgCl2 or MgSO4, Wood flour, Perlite, High Strength fiber glass mesh, Non-woven fabrics, water etc.

MGO board types:  Raw MGO board, Laminated MGO board (with PVC or HPL outer layer), MGO SIP (XPS/EPS) etc.
In many applications, MgO boards can be used in the same ways as gypsum and cement sheathings (so it is easy to use). But MgO is much more versatile with vast application possibilities.

Ceiling, ceiling linings, fascia, soffit etc
