Fire Door Core Board-MD300
The calcium silicate fire door core board is designed as a core filler material
especially for steel and wood fire doors with ratings of 60, 90, 120 minutes.
With the properties of high heat resistance, low thermal conductivity, small bulk
density and high specific strength, the product performs excellent in the aspect of
heat and sound insulation. Long term usage won't lead to deformation. The fire
door core doesn't contain asbestos. Products will help fire-rated door
manufacturers meet the demand for positive pressure fire safety requirements.
