What is MDF?

What is MDF?

MDF stands for Medium-Density Fibreboard. This is a man-made material which can be used in a variety of ways. There are two types, moisture resistant and fire retardant. They are typically labelled using different colours. The former being green and the latter either red or blue.


How is MDF made?

Medium-density fibreboards are engineered wood, made using defibration. The trees are debarked and the bark can be sold for other uses such as on-site furnaces and landscaping. It is a combination of hardwood and softwood that has been broken down into fibres.  82% wood fibres, 9% urea-formaldehyde resin glue, 8% water and 1% paraffin wax are what generally makeup MDF. The fibres are then machine dried and pressed into stable sheets.  After pressing, the sheets are cooled in either a star dryer or a cooling carousel. Eventually, it can be trimmed and sanded ready to be used in manufacturing.


Why do we use MDF?

Over the past years, Medium Density Fibreboard has become an increasingly popular woodwork thanks to its versatile uses. Unlike natural woods, MDF does not contain any knots or rings, allowing for a more clean appearance. Additionally, cutting through knots and rings is more difficult so without them, it makes the job easier. Medium density fibreboard is less expensive than many natural kinds of wood which allows for the prices of our products to be more suitable for our customers. In addition, it is consistent in strength and size and also shapes well. This material will not expand or contract, unlike other woods which is beneficial. Also, finishing MDF is much easier such as adding primer and paint.
