Medium Density Fibreboard (MDF) is a type of hardboard, which is made from wood fibres glued under heat and pressure. The boards produced are denser and more uniform in their constitution as compared to plywood or general wood.
It is dense, flat, stiff, has no knots and is easily machined. Because it is made up of fine particles it does not have an easily recognisable surface grain. MDF can be painted to produce a smooth quality surface. Because MDF has no grain it can be cut, drilled, machined and filed without damaging the surface. MDF may be dowelled together and traditional woodwork joints may even be cut. MDF may be glued together with PVA wood glue. Oil, water-based paints and varnishes may be used on MDF. Veneers and laminates may also be used to finish MDF.
Plain MDF & Prelaminated MDF boards are used to make display cabinets, wall-panels and storage units, etc.
