Medium density fibreboard (MDF) is a building and manufacturing material. The wood product is made of lignocellulosic filaments held together by an adhesive substance, such as an organic binder like resin.
The most common applications of MDF are in the construction and furniture industries. Builders and manufacturers typically use MDF panels for flooring, panelling, siding and mouldings, in addition to furniture, including cabinets, drawers and shelving.
Panels constructed from MDF are available in various sizes for different purposes. For example, thicker MDF panels of 1.25 cm (1/2 inch) or more are best for constructing panels used in furniture, and thinner MDF panels of less than 1.25 cm (1/2 inch) are frequently used for cladding.
MDF has several advantages over particleboard, including more uniform density and smoother edges that make machining easier. The International Journal of Reliability and Applications article "Exploring Graphically and Statistically the Reliability of Medium Density Fibreboard" notes that MDF is also eco-friendly because the panels are byproducts of wood waste.
