Production and characterization of MDF using eucalyptus fibers and castor oil-based polyurethane resin

the growing popularity of wooden panels renders this market segment increasingly competitive. mdf (medium density fiberboard), in particular, is widely employed for a variety of applications, including civil construction, furniture, and packaging. this paper discusses a study of mdf produced from alternative raw materials, i.e., eucalyptus fibers and castor-oil-based polyurethane resin. physical and mechanical tests were performed to determine the mdf's modulus of elasticity and modulus of rupture in static bending tests, its swelling, water absorption, moisture and density. the results of the physical and mechanical characterization of this laboratory-produced mdf are discussed and compared with the euro mdf board standard. mdf produced with eucalyptus fiber and castor-oil-based polyurethane resin presents results very satisfactory.
