what is mdf board

Medium-density fibreboard (MDF) is an engineered wood product made by breaking down hardwood or softwood residuals into wood fibres, 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 and is made up of separated fibres but can be used as a building material similar in application to plywood. It is stronger and denser than particle board. MDF is considered to be an upgrade from plywood and particle board and is used as a real wood alternative. 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) . MDF sheets come in thicknesses from 1/4 to 1 inch, and full sheets are typically 4 x 8 ft. in size (actual size is 49 x 97 inches). It is used as a building material in residential and commercial buildings and in cabinetry and furniture-making. MDF boards made with a unique surface finish are generally regarded as a much better substitute to plywood. Their smooth and refined laminate coating provides an added layer of support to the fiberboard itself, rendering it extremely durable and scratch-resistant. Laminate MDF boards are often used for making cupboard shutters, tabletops, window sills, doors, panels, and furniture making.
