Some people who mill MDF report respiratory discomfort or distress. MDF is composed of very fine fibers and a binder, either of which can be a lung irritant. Manufacturers and users generally recommend wearing a respirator when working MDF with power tools. If you aren't putting fibers in the air, though, you don't necessarily need a respirator (such as when painting or postioning a panel).
mdf is a manufactured wood material
MDF (Medium Density Fiberboard) is made of pulverized wood, wax and resin (glue).
Not at all. MDF is a man made material from hard and soft woods. There is wax and resin in MDF, both of which could prove fatal to a hamster.
MDF stands for "medium-density fiberboard. Typically, MDF is the primary material of choice for many furniture manufacturers because of its low cost and availability.
MDF is not wood. It is synthetic material that looks and feels just like wood. To the untrained eye, MDF is a great and inexpensive alternative to wood.
The weight of mdf will depend on the grade and thickness of the material. A grade mdf 3/4 inch thick in a 49x97 inch sheet size weighs roughly 96 lbs.
MDF (Medium Density Fibreboard) is made from waste wood fibres which are glued under heat and pressure. It is very versatile, but can be dangerous to use if proper safefy precautions are not adhered to. Most MDF slowly releases urea formaldehyde which is an irritant to the eyes and lungs. This can be sealed in with proper preparation and painting. The dust produced when sanding or cutting is another matter, and masks and goggles should ALWAYS be used when machining or cutting this material, and adequate ventilation should be present in the work area.
It's not a bad material. It just may not be good for certain applications.
The best material for entertainment center cabinets is MDF (Medium Density Fibreboard) The MDF is easy to saw, mill, paint and handle. It is a very solid material sou it will not easily cause vibrations, if you turn the volume of your entertainment centre high.
MDF is not as strong as plywood, or as strong as a hardwood, but it is stronger than low density fibreboard or softboard. It can be as strong as some softwoods, but because it has no grain, it will not have the strength this gives in two dimensions. It has the advantage of being a very consistent material.
Short answer; It depends where the MDF comes from. Long answer: First of all there are different grades of MDF. Most are listed by the density. This density is from the cubic weight of the board not the species. MDF is made from either hardwood or softwood depending on where in the world the MDF is produced. Most MDF is made from the scrapes of wood from dimensional lumber mills or waste recycled wood from demolition projects. Most dimensional lumber is made from fir and southern yellow pine. So MDF mills mix both species if the raw material gets limited. In the United States most MDF mills are in rural areas near large tracts of forests so what ever the native species of wood is what makes up the MDF. In the North east hardwoods are used. Maple, Oak and cherry are the primary raw material. In the mid Atlantic region there is a mixing of species. Primarily in Pennsylvania, New York and Virgina the raw material is hardwood but most mills are using up to 20% pine softwood in their MDF. In the majority of the MDF mills in the south use southern yellow pine due to the abundance of the raw material. The northern and western United States as well as most of Canadian MDF mills use a mix of southern yellow pine and fir. Some mills in the Midwest and west coast have begun making MDF out of straw.
