Medium density fiberboard or MDF as it is commonly known in the construction field is a very useful material. It is made up of waste products from lumber yards and has a resin mixed with it to make it smoother. The particles used in the makeup are smaller and therefore makes for a much less tear out and leave a smooth edge when sawed, rather than a jagged one. It also means that a coat of primer and a couple coats of paint make these panels very attractive finished surface. Most other products like plywood or fiberboard will not have the same effect. It is also a strong material with a low reaction to humidity. This makes it even more useful in household applications. One word of caution, use a mask and eye protection when cutting or sawing due to the toxicity of the resin particles. As with any particles you don't want to breathe them in or get them in your eyes.
