This is to introduce us as one of the biggest manufacturers on interior/exterior drywall of magnesium fireproof boards in China.Now we avail ourselves of this opportunity to write to you and see if we can establish business relations by a start of some practical transactions.
Our magnesium fireproof board is strong as hardwood plywood. Our fireproof board is fireproof, waterproof, sound insulation etc. And our fireproof board does not content any asbestos, formaldehyde, benzene or other harmful element. You can easily cut, saw, drill, nail, paint and veneer our fireproof board, just like gypsum board.
The followings are the parameters of our fireproof board.
1. Fireproof
The fire-resistant grade of 8mm thickness board is over 120 minutes. The fire resistant grade of thicker board is higher than 8mm thickness.
2.Waterproof and Moistureproof
You can immerse our fireproof board into water for one month. When you take it out from water, our fireproof board keeps its original shape without deformation or expansion.
3.Strength
Our fireproof board is strong as hardwood plywood. Our 8mm thickness flexural strength is over 20Mpa. The thicker board is stronger.
4.Sound insulation
The sound insulation of 10mm thickness fireproof board can reach 50dB. Our fireproof board have good noise insulation property.
5.Environmental
Our fireproof board is made of inorganic mine chemical materials. So our fireproof board does not content any asbestos, formaldehyde, benzene or other harmful element.
The other characters of our fireproof board is light, heat insulation, preventing frostbite, anti-insect, anti-mildew, flexible etc.
Our fireproof boards can be used instead of plywood, and also used as interior/exterior drywall and ceiling board.

And the Chinese still think they're communists... :-)
It appears that magnesium fireproof board is a popular product in China. However, I'd be a little leery of products that promote themselves as meeting US Standards. For example, I checked out one manufacturer's website which stated they were ASTM and UL Certified...ASTM doesn't certify products or materials. Additionally, it stated they had ICC certificates available...ICC doesn't issue certificates, and ICC-ES doesn't even list an evaluation report for that one manufacturer's product. |

I make allowances for that mistake, because the way I spell my name is the masculine form (think Lynn Dickey, Lynn Swann) |

Magnesium fireproofing? I remember that we held a flame to a small strip of magnesium in high school chemistry class and it burned brighter than the sun and faster than a firecracker fuse. Yeah, that was before "safety" was invented and common sense was still in its infancy.
That same chemistry teacher also demonstrated the reactivity of metallic sodium by dropping a sugar cube-sized piece into a bucket of water. Fortunately, we were out-of-doors but the ensuing explosion broke about twenty window panes in the court yard of the school.
Caveat emptor. |

James - Thank you! I thought I remembered the same thing about magnesium (and metallic sodium, too, for that matter) but wasn't sure. Yet the web site cited above appears legitimate. It's an interesting read, too. When was the last time you used "glabrous" to describe a product?
It's certainly a different concept and doesn't appear to be in the same category as the email I got from Charles Taylor's second wife. |

The material actually used is magnesium oxide, which has a very high melting point (2800 deg C). It is combined with fiberglass fibers, talc and other fillers to form a panel. Some products have passed ASTM E 84 for surface burning. |

I just this morning found DragonBoard US in 4specs Gypsum Board section. It says it's MgO (magnesium oxide). Lots of tests. No address and no indication of where it is made on the web site but their Manu-Spec says

Their premise seems to be a relpacement for drywall sheathing, but with a single layer having the performance of a double layer of GWB. The product is much more money (their own figures), relying on the labor savings of a single layer to make it competitive.
I have concerns about quality control. China is still, apparently, a "wild west" (or east, I guess) capitalism. As recent news attests, there's very little regulation and highly varied quality control. I'm sure many products are fine, but maybe there's no way to be sure without testing every batch that arrives at the job site. |
