MDF in Brazil is an almost recent product, available in the market from the late '80s. The resin content appears as one of the factors that most influence the final properties of MDF panels. Identification of how these factors interact is very useful for improving performance and energy inputs, determining ideal resin content based on the desirable...

... Although Brazil's share in the production and consumption of wooden panel was not significant in the past, this situation has been changing in recent years owing to new investments in board production units, especially, particleboards and MDF [4]. This increase production is also attributed to the increasing use of boards in some industrial sectors, e.g., cabinetmaking, civil construction, packaging, etc. ...
... MDF is manufactured to dry, made of fibers lignocellulosics, combined with resin, and compacted by hot pressure. MDF is a nonstructural wood-based panel that is composed of wood fibers bonded together with resin under heat and pressure [4,5]. In recent years, great changes have taken place in the MDF industry. ...
The medium density fiberboard (MDF) is a wood derived product. The wood-based panel is normally produced
with urea-formaldehyde, melamine-formaldehyde and/or phenol-formaldehyde adhesives. However, the former is considerably toxic and environmentally damaging, while the lather is expensive, thus motivating the search for alternative raw materials in fiberboard production. This research discusses a study of MDF produced from alternative Castor oil based polyurethane adhesive and Pinus caribaea var. hondurensis fibers. The castor oil based polyurethane resin developed at the São Carlos Institute of Chemistry, University of São Paulo, is an environmentally friendly vegetal oil-based polymer that is harmless to humans. The Pinus caribaea var. hondurensis offers favorable properties for fiberboard manufacture. The MDF’s performance was evaluated based on the results of physical and mechanical tests recommended by the European standard (EC). Tests results showed higher values than those recommended by the European standard, indicating that the Castor oil-based polyurethane resin is promising adhesive for the manufacture of MDF.
