Properties of MDF boards

MDF boards have come up in the last decades of the twentieth century and have since become more widespread. They are especially prized for their excellent product properties and the variety of processing options. In this guide you will learn more about the versatile properties of MDF boards.

Background knowledge on MDF boards

MDF boards were developed in the USA and found their way to Europe relatively late. Today, they are indispensable for interior design, furniture construction and many other projects. They are made on the basis of wood fibers, so they are a wood composite material. In total, MDF boards consist of the following components:

  • wood fibers
  • Glue or glue
  • different ingredients
  • water

Construction of MDF boards

The wood fibers are fiberized so small that it can not come to a uniform fiber direction during subsequent pressing. Thus, the plates are neutral on all sides and no fiber direction subject. This makes the MDF boards extremely abrasive. Even sawing out sharp profiles is no problem at all.

Distinction of MDF on the density

Due to the high density of MDF, even edges and corners need not be specially reinforced, or rounded off as with other composites to prevent breakage of parts of the panel. The density also provides information about which type of MDF boards are concerned:

  • Lightweight MDF: less than or equal to 650 kg / sqm
  • Ultralight MDF: less than 550 kg / sqm
  • HDF: greater than or equal to 800 kg / sqm

However, these distinctions can no longer be found in standardization (they were part of DIN EN standardization).

Properties similar to wood

This means that the density of MDF can also be influenced and be very different. In addition, MDF behaves like ordinary wood - it can store and release moisture. Thus, the use in outdoor areas or in wet areas is only partially possible or requires specially processed MDF.

Limitations of MDF by its properties

The plastering of MDF boards is a problem not only because of the high density and thus very smooth surface. At the same time, an MDF panel would quickly drain too much moisture from a regular plaster.

Ingredients in MDF

But that's not enough. The chemical ingredients can lead to outgassing, which colorize the plaster irregularly brown. In addition, release agent residues may remain on the surface of MDF boards as a result of the manufacturing process.

Transparency in production

In general, when using MDF panels you should only use products whose manufacturing process is completely transparent. As a result, MDF panels are virtually eliminated from outside the European Union. It could never be guaranteed that hazardous substances do not tend to outgas and evaporate.

Conclusion MDF boards: properties similar to wood, only better

The properties of MDF boards are similar to those of conventional, normal wood. Only that the attributes of MDF around classes allow better edits and processing. More about processing MDF boards we have summarized here for you.

Tips & Tricks

Since MDF boards have such excellent properties, they can be used as a low-cost and easy-to-machine base carrier in furniture construction. Thus, the veneering of MDF boards has a high priority and is one of the typical processing methods of MDF boards.
