Basic classifications of MDF (Medium-density Fiberboard)

Medium-density fiberboard (MDF) can be classified by density into: high-density fiberboard (HDF), medium-density fiberboard (MDF), and low-density fiberboard (LDF) (MDF density ranges from 0.65 g/cm³ to 0.80 g/cm³, while HDF density is ≥0.80 g/cm³).

 

The national standard (GB/T 11718-2009) classifies it into: Ordinary MDF, furniture-grade MDF, and heavy-duty MDF.

 

Based on application, MDF can be classified into: Furniture boards, flooring substrates, door panel substrates, electronic circuit boards, milled boards, moisture-resistant boards, fire-resistant boards, and molding boards, etc.
