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 panels by applying high
temperature and
pressure. MDF is generally denser than
plywood. It is made up of separated fibres, but can be used as a building material similar in application to plywood. It is stronger and much denser than
particle board.
