Production and Properties of Isocyanate-Bonded MDF Manufactured from Acacia Mangium

Medium density fiberboards (MDF) were manufactured from fast-growing Acacia mangium wood. The boards were produced at two levels of density, 600 and 750 kg/m³. Isocyanate and urea- formaldehyde resin adhesives were used asbinders. The physical, mechanical and dimensional stability properties we...
