Sanded MgO Board
Features
1.Fire prevention and stop burning
Sanded mgo board contains limited organic fiber that could easily pass fireproof test EN 13501-1:2007 and ASTM E 84-12 with excellent result. Smoke development(SDI)<30, meet Class A.
2.Durability and long life service
Sanded mgo board is breathable wall panel could adjust in house moisture content, not too dry or wet. Dimension stable during moisture move from 30%-90%. It will not mold or soft in wet environment.
3.Sound insulation
Sanded mgo board sound insulation of 12mm 39(DB)
4.Keep warm and insulate heat
Sanded mgo board has low thermal conductivity 0.218W/m.K,tested to ASTM C 158.
5.Surface smooth and flat,Convenient process
Thickness<0.1mm, width and length<1mm
6.Green environmental protection
Certified non-corrosive mgo board can be safely connect with steel and metal parts. It does not contain any formaldehyde and asbestos or any harmful substance.
