 Medium-density fibreboard
Medium-density fibreboard (MDF), is an engineered wood product formed by breaking down softwood into wood fibres, combining it with wax and resin, and forming panels by applying high temperature and pressure.
Low density fibreboard, such as caneite, ranges in density from 160 to 450 kg/m³, while high density fibreboard, such as masonite, has a density of around 1000 kg/m³.
Its name derives from the distinction in densities of fibreboard.

 Wood Composites - Recent Publications
Abstract: Due to the moisture and temperature gradients developed during hot pressing of medium density fibreboard (MDF), residual stresses occur within the board as it equilibrates to room conditions.
The face density region of the density profile was further described as either a narrow density peak or a wide density peak, referring to the degree of density change within the face itself.
The greater thickness swell in the surface layers of MDF suggests that efforts to improve dimensional stability of MDF should be focused on stabilizing the high-density surface layers.
