Factory Direct selling lower price and high quality expanded perlite plate
The main material of the board is Magnesium Oxide.
The board is an environmental protection product.It`s a kind of new fire proof filling material and insulation material.
Features and advantage:
1,environmental protection,non-poisonous,zero radioactivity
2,fire proof,keep warm,moistureproof
3,Corrosion Free,rustless
As stated above, our product is pressing-made under high temperature and pressure, and moisturecontent is strictly controlled not more than 8%. However, the issue of rustiness in steel door or galvanized steel sheet was unable to solve due to high moisture content while traditional processing.
4, light,hi-strength,anticorrosion,non-aging
5, Less production procedure and workload:
We can manufacture most satisfied product according to customer requirements, even some special sizes.And our product is cut under control by computer, size is very accurate ,making it a whole board to put into doorframe, no extra cutting or assembling is needed, which reduce a lot of procedure and work not necessary,saving your money and time.
6, The combustibility achieves accord with GB8624-2006A1 level product.
