Magnesium Oxide Boards

タイトルまたは説明

Main characteristics
 

 Magnesium  Fireproof Board was tested by the National Center for Quality Supervision and Testing of Fire Building Materials (NFTC). Its fireproof level is rated level A (nonflammable level)

2 Moisture-Resistance

 

Magnesium Fireproof Board is excellent in moisture-resistance. Dry bending strength is *5Mpa. Bending strength under absorbed moisture is *2Mpa.

3 Heat Insulation

 Magnesium Fireproof Board has heat prevention material incorporated, it has great feature of heat prevention. Thermal resistance is 1.*4m2k/w.

4 Sound Insulation

 Magnesium Fireproof Board is proved to have good noise insulation property after inspected by the National Center for Quality Supervision and Testing of Fire Building Materials (NFTC), The noise insulation factor of the wall can reach *4dB and *7dB. It has the best noise insulation constitution in China, especially the *5mm wall comprised by the *0mm board.

5 Bump-resistance and light

 Magnesium Fireproof Board is a light board. Its density is less than 1.0×1.*3kg/m3. At the same time its bending strength and impact resistance is excellent. Also, it will maintain its' quality during construction. It is light, t can save time, space, weight and expense. It is a new and high efficient wall.
