Brazil is among the world's most advanced manufacturers of reconstituted
wood panels. It is also the coungry with the greatest number of state-of-the-art panel plants. With continual investment in technology and automation, its companies are constructing versatile, modern industrial complexes for the installation of new production lines. They are also investing to modernize the
technology in their existing plants, introducing continuous press production lines and adding new printing, 'glue' impregnation, laminating and painting rocesses

Definition
MDF is a reconstituted wood panel like MDP and HDF. MDF is the acronym for ‘Medium Density Fibreboard’. The wood fibres are glued and compressed with synthetic resin through a combination of heat and pressure in the latest generation of a continuous press.
MDF is a homogenous industrial panel with excellent dimensional stability, even surfaced, smooth and of a high density.
Base raw material
These panels are produced with pine and eucalypt wood, cut from sustainable cultivated forests, so MDF board is an environmentally friendly product.
Finishing options
Natural, laminated or painted.
1. Natural (without covering)
The panels are left uncovered, ready for processing by the user and can be surfaced with wood veneers or with plastic laminate such as PVC. Another finish is by painting or printing directly onto the board.
2. Low pressure laminated
Low pressure lamination is where a paper-based sheet, impregnated with melamine resin, is applied to the board with a combination of heat and pressure, producing a panel ready for use. MDF can be smooth, textured or decorated in plain colours, with a wood grain pattern or a fancy design. Low pressure laminate provides a finish highly resistant to surface scratches and stains, as well as to an infestation of micro-organisms.
3. Finish foil (FF) or ecological laminate (LE) covered
A specially varnished paper-based overlay is laminated to the MDF panel through a process of heat and pressure. The MDF board is supplied in a plain colour, a wood grain pattern or a fancy design with various finish options including standard, coatable or ready coated in a high gloss or semi-matt varnish.
4. Painted (high gloss or semi-matt)
The MDF panel is painted or lacquered in a plain colour, a wood grain pattern or a fancy design.
Uses and applications
Because of its characteristics, MDF is widely used in the furniture industry for the front of pieces that are machined or embossed, on the back of furniture, for the sides and base of drawers, and also in crafted pieces of furniture. In the construction area, MDF is used to make laminate floors, skirting boards, embossed moulded doors, door jambs, routed door faces, shaped parts like stair banisters, table legs and also for packaging.
Maintenance and cleaning
Cleaning finished wood panels must be carried out with a clean, soft cloth, dirt-free and dry or lightly moistened with mild soap and water, squeezed out thoroughly to remove excess water. Abrasive material such as steel wool or sharp objects should not be used to clean MDF. To remove stains, use a cloth dampened with a solution of alcohol and water in equal measure.
