Thermal Insulation Door Core Board
Thermal Insulation Door Core Board

    Fireproof door core board is a new generation of non flammable fire protection products, mainly natural magnesium oxychloride or Magnesium Sulfate inorganic environmental protection materials, through the mechanical flow operation compounded, can be cut, can be planed, saw, can be carved. Through the polishing and paving treatment, the surface is smooth. It is suitable for the roof, decoration, partition, insulation, insulation, fireproof door lining, fireproof separation, and special lining board for purification board. It has the characteristics of non flammable, non explosive, water resistant, oil resistant, chemical resistant, non-toxic and high mechanical strength.


1、Natural environmental protection, nontoxic and tasteless, no radioactivity.
2、Non flammable, fireproof, waterproof, corrosion resistant.
3、The construction is convenient, light weight, heat insulation, sound absorption and good heat preservation.
4、Tangent, planing, sawing, and carving.
5、Conform to the national standard GB8624-2006A1 grade non combustible standard, light weight, high strength, no aging, corrosion resistance.
6、Through national standard GB/T20285-2006 AQ1, safety first class environmental protection products.
