"Medium-density fibreboard (MDF) is an engineered wood product made by breaking down hardwood or softwood residuals into wood fibres, 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. It 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."

"Just like particle board, MDF will soak up water and other liquids like a sponge and swell unless it’s very well sealed on all sides and edges. Because it consists of such fine particles, MDF doesn’t hold screws very well. Because it’s so dense, MDF is very heavy, making it more difficult to work with. MDF can’t be stained.  Not only does it soak up stain like a sponge, but because there’s no wood grain on MDF, it looks awful when it’s stained. MDF contains VOCs (e.g. urea-formaldehyde), so care needs to be taken while cutting and sanding to avoid inhalation of the particles. MDF is generally cheaper than plywood. The surface of MDF is very smooth, which makes it a great surface for painting. MDF is consistent throughout, so cut edges appear smooth and won’t have voids or splinters. Because of the smooth edges, you can use a router to create decorative edges. The consistency and smoothness of MDF allow for easy cutting of detailed designs (such as scrolled or scalloped designs) using a scroll saw, band saw or jigsaw. I hope this answers your question."

"Medium density fibreboard is a breakdown of hardwood and soft wood into fine particles then re binder by resin and wax at high pressure"
