 Performance for Fireproof Mgo Gray Board Substitute for Gypsum Panel

(1) Fireproof Board

standard mgo 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

standard mgo board is excellent in moisture resistance. Dry bending strength is 15Mpa. Bending strength under absorbed moisture is 22Mpa;

(3) Heat Insulation

standard mgo board has heat prevention material incorporated, it has great feature of heat prevention. Thermal resistance is 1.14m2k/w;

(4) Sound Insulation

standard mgo 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 44dB and 47dB. It has the best noise insulation constitution in China, especially the 95mm wall comprised by the 10mm board.

(5) Bump-resistance and light

standard mgo board is a light board. Its density is less than 1300kg/m3. At the same time its bending strength and impact resistance is excellent. Also, it will maintain its' quality during construction. It is light, it can save time, space, weight and expense. It is a new and high efficient wall.
