MEDIUM DENSITY FIBERBOARD

Medium-density fiberboard (MDF) 

An engineered wood product made by breaking down hardwood or softwood residuals into wood fibers, 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 more dense than plywood. It is made up of separated fibers, but can be used as a building material similar in application to plywood. It is stronger, and more dense, than particle board.
