Foamed MGO Board for Fireproof Door Core Use

Foamed MgO board fireproof door core


Product description:
Expanded perlite is a kind of product with characteristics of non-toxic, odorless, non-combustibility, corrosion resistance,
acid-base resistance, insulation, sound and thermal insulation and honeycomb interior structure. It is a white or light-colored
superior thermal insulation material made through smashing acid volcano glass lava, screening to a certain granularity, preheating
again, and sintering under high temperature of 1400°C. And it can be compounded with different adhesive into hydrophobic perlite
insulation board, perlite sound absorption board, partition board, fire proof board, etc.

Specification:
1) Thickness: 25mm, 36mm, 48mm, 50mm
2) Size: 900mmx2100mm, 900mmx1900mm etc.
3) Special sizes available upon requests

FAQ:
What is the largest size?
A: 900x2100mm.
What is the largest density?
A: 310kg/m3. But the density we can ensure is 300kg/m3. Tolerance -10kg/m3 to +10kg/m3. Our foamed MgO door core board is made by mold, so the density will not be very accurate.
