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.
