Production of wood fibre boards (MDF/HDF)
Fibreboard usually has a homogeneous structure, which is finer than that of particleboard. They can therefore be processed similarly to solid wood, i.e. it is possible, for example, to mill or profile them. A distinction is mainly made between MDF (medium density fibreboard) and HDF (high density fibreboard). The trend is towards particularly thin fibreboard from 1 mm thickness (THDF and UT-HDF).
Medium density fibreboard (MDF) was invented in the USA and became more widespread in Europe at the end of the 1980s. MDF is mainly used in the furniture and flooring industry as well as in interior design. Other areas of use for MDF include doors, interior trim, applications in the automotive industry, the construction industry or in semiconductor manufacturing. The boards can be veneered, laminated, painted or otherwise coated. Boards with a thickness of 1.2 mm to 60 mm are produced. The density can range from 600 kg/m³ to 1200 kg/m³. Boards with a density of more than 800 kg/m³ are usually known as HDF. These are mainly used as carrier boards for the flooring industry (laminate flooring). A total of around 100 million m³ (2016) MDF/HDF boards are produced worldwide. The largest capacities are in China, Turkey and Brazil.
