Core-filling materials play a decisive role in the fire resistance of fireproof wooden doors. They should have the characteristics of low thermal conductivity, small volume and good processing performance, and help to improve the fire resistance of the door = reduce the weight of the door, eliminate or reduce the initial wood door Deformation (corners, warpage). The fire-resistant wooden door made of 32VL flame-retardant material has a fire resistance time of 68 min
