MgO expanded fireproof door core
Introduction:
Fireproof door core is the new generation of fireproof filling material and sort of natural and environmental product, and it reaches fireproof Grade A1 according to National Fireproof New Standard combining application with steel or wooden door.
The panel is a new kind of A-class non-combustible insulation materials of wall. It was based on the inorganic adhesive material, glass beads and fire-retardant foam materials for light aggregate. And add a variety of polymer additive, after modification, the modifier in a pressure molding line, then through the late maintenance and cut.
