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.^[1] 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.
