MDF Technical Specifications

MDF (Medium Density Fiberboard) is a homogeneous panel made of wood fibers. The wood is pine from reforestation, bonded with thermoset synthetic resin and special additives under the simultaneous action of pressure and temperature.

MDF is specially developed for internal use. This correct utilization ensures that the plates maintain their dimensional and physical characteristics.

Sudati produces MDF in two different ways.

The first one, uncoated, is ideal for painting. Offered in thickness of 6mm, 9mm, 12mm, 15mm, 18mm and 25mm.

The second way is coated with low pressure melamine paper low pressure, bonded with pressure and heat, available in white in thickness of 6mm, 9mm, 12mm, 15mm, 18mm and 25mm, coated on both sides or only on one side of the panel. For other standards, we provide our panels in thicknesses of 6mm, 15mm, 18mm and 25mm, coated on both sides in all thicknesses, and one face only 6mm.

The production of Sudati process respects the following physical and mechanical properties, based on ABNT NBR 15316-2:
