Medium Density Fibreboards (MDF) are the most widely spread type of fibreboards manufactured by the dry process, i.e. by binding wood fibres together with synthetic resin adhesives.
The typical production process starts with chipping of the wood. The chips are then softened by the influence of high temperature and moisture and mechanically reduced to fibres. The fibres are then mixed with an adhesive, dried and formed into a mat before pressing. The mat is then pressed down to boards of the desired thickness between heated and polished press platens. According to their density, the boards are differentiated into MDF, high density (HDF), light (LDF) and ultra-light (ULDF) fibreboards manufactured by the dry process.
MDF can be made from softwoods or hardwoods. The majority of MDF manufactured in Europe is made from softwoods.
MDF has high bending strengths and tensile strengths perpendicular to the plane of the board (internal bond) and smooth surfaces on both faces. Coated MDF is used predominantly in furniture and in laminate flooring. Raw boards are used more and more for interior trim and roof furnishings.
