MDF refers to medium-density fibreboard. These boards are produced in a dry process by bonding wood fibres and synthetic resin adhesives. In addition, additives such as paraffin are used to create additional properties.
MDF is suitable for use in the construction industry, for the production of laminate flooring and for furniture construction.
MDF is divided into three subcategories:
MDF can be made from hardwood and softwood. In Europe, MDF is mainly produced from coniferous wood. Urea-formaldehyde resin (UF), phenolic resin (PF) and polymeric methylene disocyanates (PMDI) are used as adhesives.
For production, wood is shredded into wood chips. After thermal softening, these are then mechanically dissolved into wood fibres. The fibers are mixed with the adhesive and formed into a mat. These mats are pressed between polished and heated press boards to form MDF boards.
MDF boards can be improved with additives in terms of fire protection, strength and moisture resistance. Surface treatments such as painting and coating are also possible.
is available in thicknesses from 1.5 to 60 mm. As a rule, the common plate formats measure widths of 2070, 2440, 2650, 2850 mm and lengths of up to 6300 mm.
