Medium-density fibreboard
Medium-density fibreboard (MDF) is an engineered wood product made by breaking down hardwood or softwood residuals into wood fibre, often in a defibrator, combining it with wax and a resin binder, and forming it into panels by applying high temperature and pressure. MDF is generally denser than plywood. It is made up of separated fibre but can be used as a building material similar in application to plywood. It is stronger and denser than particle board.
The name derives from the distinction in densities of fibreboard. Large-scale production of MDF began in the 1980s, in both North America and Europe.
Over time, the term "MDF" has become a generic name for any dry-process fibreboard.
MDF is typically made up of 82% wood fibre, 9% urea-formaldehyde resin glue, 8% water, and 1% paraffin wax. The density is typically between 500 and 1,000 kg/m3 (31 and 62 lb/cu ft). The range of density and classification as light-, standard-, or high-density board is a misnomer and confusing. The density of the board, when evaluated in relation to the density of the fibre that goes into making the panel, is important. A thick MDF panel at a density of 700–720 kg/m3 (44–45 lb/cu ft) may be considered as high density in the case of softwood fibre panels, whereas a panel of the same density made of hardwood fibres is not regarded as so. The evolution of the various types of MDF has been driven by differing need for specific applications.
The different kinds of MDF (sometimes labeled by colour) are:
In Europe, MDF is classified for use by the standard EN 622-5, such as load-bearing for general dry or humid conditions. The light and ultralight MDF are also classified by EN 622-5 for general (non-load-bearing) use.
Although similar manufacturing processes are used in making all types of fibreboard, MDF has a typical density of 600–800 kg/m3 or 0.022–0.029 lb/in3, in contrast to particle board (500–800 kg/m3) and to high-density fibreboard (600–1,450 kg/m3). In addition, MDF typically has an MOR of 40 MPa and an MOE of 3 GPa. Because it is easier to machine and has good weathering characteristics, it tends to replace particleboard in applications such as furniture, cabinet making, joinery, craft work and flooring.
In Australia and New Zealand, the main species of tree used for MDF is plantation-grown radiata pine, but a variety of other products have also been used, including other woods, waste paper, and fibres. Where moisture resistance is desired, a proportion of eucalypt species may be used, making use of the endemic oil content of such trees.
