fireproof board/ glass magnesium board /mgo board /magnesium oxide board/ lightweight partition board
Product features:
1) High strength, light-weighted and economical
2) Non-flammability: conforms to the national grade A1 standard (GB8624-2006 Grade A1). And in case of fire, the board will not burn and not give off poisonous smoke
3) water resistant: The product is allowed to long-term expose to moist environment. Even dried in open air after a few days soaking in water, it will not deform or shrink.
4) Invariability: Resistant to deformation in wet, hot and dry conditions
5) Sound insulation: Sound loss through a 9mm thick Tolar TM plate -42dB
6) Heat resistance and preservation: Thermal conductivity of 0.216w/mk
7) Durability: Resistance to corrosion, acid and alkali, long lasting strength
8) Frost resistance: can be exposed at -40 degree
9) Easy installation: easy to cut, saw, nail, drill, stick, and paint. The board has unique smooth and rough surface, the form finish can be sticked with wallpapering, aluminium panels, veneer, pvc, or get painted or sprayed, while the later for tile, marble, granite, etc.
10) Environmentally friendly: free of asbestos, formaldehyde, ammonia and other toxic substances.
11) Anti-insects and mildew: The board provide good insulation against insects, fungus and corrosion.
