As the industry becomes more developed, the “MDF” is becoming a term which for any dry-process fibre board. Typically, the MDF is made of 82% wood fibre, 9% resin glue of urea-formaldehyde, about 8% is water and 1% is paraffin wax. Generally, the density typically is between 500kg/m3 to 1000kg/m3. There is also a range of density for classification as light, standard and high density board. The density of the fibre which goes into making the panel is related to the density of the board. For instance, a thick MDF panel which has a density of 700-720 kg/m3 is considered as a high density in case of the material is softwood fibre. But a hardwood fibres made panel of the same density may not regarded as so. The evolution of the different types MDF boards have been driven by different need for a specific application.
