[0002] Medium-density fiberboard (MDF) is a type of fiberboard made from wood fibers or other plant fibers. The fibers are prepared, coated with synthetic resin, and pressed under heat and pressure. Based on its density, it can be classified into high-density fiberboard (HDF), medium-density fiberboard (MDF), and low-density fiberboard (LDF). The nominal density of medium-density fiberboard ranges from 650 kg / m³ to 800 kg / m³. Due to its uniform structure, fine texture, stable performance, impact resistance, and ease of processing, MDF is widely used in furniture, decoration, musical instruments, and packaging in China.
