Raw Materials

Magnesium Oxide (Mgo), Magnesium Chloride, Perlite, Sawdust, Fiberglass Mesh, Non-Woven Cloth Etc.


1) Many advantages: paper magnesium fireproof board has many advantages just as fireproof, moisture-resistance, heat insulation, sound insulation, high strength
and light. These advantages are tested by authorities

2) Easy to install

3) Good effect: paper magnesium fireproof board will not break during installation,
so it could give customers a perfect decorative effect

4) Environmental friendly: paper magnesium fireproof board is made of natural inorganic material. It does not contain asbestos and methyl alcohol. It is low radiation. The environmental friendly effect is in accordance with the national standard

5) Competitive price: because of the large output and the high technology using in producing the board, the price of the paper magnesium fireproof board is competitive in the oversea market

1) Fireproof: paper 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
3) Heat insulation: magnesium fireproof board has heat prevention material incorporated, it has great feature of heat prevention

4) Sound insulation

5) Bump-resistance and light: magnesium fireproof board is a light board. Its density is less than 1.0 x 0.8kg/cbm, lighter than Magnesium Fireproof Board. At the same time its bending strength and impact resistance is excellent. Also, it will maintain its’ quality during construction. It is light, can save time, space,weight and expense. It is a new and high efficient wall
