There are three kinds of fiberboard--low-density, medium-density and high-density. All three are made by mixing powdered wood fiber and adhesive, then pressing them in a hydraulic press. Low-density fiberboard is made by compressing a foot-thick pile of fiber to 1/2" thickness. Medium-density fiberboard compresses a foot of fiber to 1/4" thickness, and high-density fiberboard compresses a foot of fiber to 1/8" thickness. Low-density fiberboard is usually coated with asphalt on one side and used as cheap sheathing under siding on houses. Medium-density fiberboard is used for a multitude of purposes, and high-density fiberboard is used for laminate flooring.
MDF or medium density fiberboard is a man-made product.
The differences between medium density and high density fiberboard (mdf and hdf) do vary slightly between manufactures. These are some general facts. MDF is a product of soft woods that are broken down by a defibrator, added to wax and resin, and formed from heat and pressure. The majority of the wood comes from saw dust. It is moderately resistant to termites and mold. It can be quite moisture sensitive. HDF is made in a similar process as MDF, but is much more dense and made from exploded wood fibers and quite a bit more pressure. HDF is highly resistant to mold and infestation and not nearly as sensitive to moisture as MDF.
One type of man-made wood is blockboard. It is made by glueing thin strips of wood from edge to edge, and then sandwiching them between veneers of wood which is then glued on under higher pressure. There is also another type called plywood.
Some household items made from MDF include cabinets, shelves, desks, and bed frames. MDF stands for medium-density fiberboard. MDF is denser than plywood.
MDF, or Medium Density Fiberboard, is made of compressed saw dust held together by resin. It is a very common material for mass-produced furniture because it is much cheaper than solid wood and sturdier than particle board. Because it is made from recycled wood and otherwise unusable wood scraps, it is also considered environmentally friendly.
It stannds for medium-density fiberboardand it is a type of wood Medium-density fiberboard (MDF) refers to a type of manufactured composite board used to make furniture, doors, flooring and walls. The making of MDF began in the United States in 1966, according to the University of Tennessee. :) If you want more type in things like history of MDF it will give you alot more
High-density lipoproteins are made of lipoprotein particles, several proteins, some cholesterol, phospholipids, and a few triacylgylcerol.

MDF stands for "Medium Density Fiberboard". MDF is a man made product, it is not a natural wood like oak or pine. MDF is made from various hardwood and softwood trees and is usually sold in large sheets.
hardboard, particleboard, insulation board, medium-density fiberboard (MDF), waferboard, oriented strand board (OSB), and other panelized products made from wood chips and particles.
clamps can be made of metal, wood and even high density plastic
