Introduction of density board classification:
According to density, it can be divided into high density fiberboard(HDF), density of high density fiberboard ≥800 kg/m3.
medium density fiberboard(MDF),density of medium density fiberboard is 650 kg/m3 — 800 kg/m3.
low density fiberboard(LDF)
The NATIONAL standard (GB/T 11718-2009) is divided into: common TYPE MEDIUM density fiberboard, furniture type medium density fiberboard and heavy duty medium density fiberboard. Can be divided into: furniture board, floor substrate, door substrate, electronic circuit board, engraving and milling board, moisture-proof board, fire-proof board and line board. The commonly used size is 1220mm*2440mm,1830mm*2440mm,1830*3660mm. Main thickness: 2.4mm, 2.7mm, 3mm, 4.5mm, 4.7mm, 6mm, 9mm, 12mm, 15mm, 16mm, 18mm, 20mm, 25mm, 30mm.
