Medium Density Fiber (MDF) is a building material used for construction purposes. It is made by the breakdown of hardwood and softwood with resins and wax to form wood fibers. It is much denser than the normal plywood board and came into being in late 1980s. It is mainly used for making closets and drawers.
MDF is very versatile in use and can be coated with any color of user's choice. The molecular level structure of MDF is such that color applied to MDF has a very good binding. It can take up a variety of paints like varnishes, water based paints or even oil based. However, the disadvantage of MDF is it can blunt sharp edges of construction equipment due to an extensive use of glue in its making.
Unlike wood, MDF does not have knots and a grainy structure. This helps in easy cutting and fitting of this material. It can be drilled quite easily. On the down side, MDF can affect your health. Formaldehyde, used in its construction is released when MDF is cut. If you come in contact with it, it may lead to irritation in eyes and lungs. Hence, it is important to wear masks and goggles while cutting MDF.
This is the biggest plus point of MDF due to which it is used these days. It is very easy to put MDF to use. Wood glue can be used to join two pieces of MDF together. Pieces can also be connected very easily through nails. The flexibility accorded in its usage helps a lot in construction activities.
Reasons for Popularity
Despite its downside, MDF is used prolifically. This is because its advantages outweigh its disadvantages by quite a margin. MDF can also be molded into different qualities as the fibers of MDF are very thin. You can do so by adding resins (UFP 1001) and additives.
