... thin MDF (density lower than 800 kg/m3) ... As an example, thin MDF has an advantage when it has to be laminated, due to its more porous and matte surface. Moreover, its internal structure is smooth and not layered like hardboard, and it does not have the tendency to split when submitted to tension. As a consequence, thin MDF is generally preferred to hardboard for the manufacture of laminated doors and furniture elements.
